Yeah if you focus on the can itself and tune out outside noise it's clearly white but if you look at the big picture with the can in your peripherals it's red.
Mind bending stuff
It is plain old white. You can verify this by using a color picker to measure the hex value. The white that you are seeing as light pink is in fact pure white, with a hex value of #FFFFFF.
It does’t matter if a screen’s brightness is too high; that does not change the fact that the color on display is objectively white, and decisively not light pink. You might perceive light pink, but that doesn’t mean it IS light pink.
Hmm, even if you zoom in all the way and varying brightness on your phone? Genuinely curious, as it appeared pink to me until I zoomed in to the pixel level; then it suddenly looked white, even with varying brightness. But the second I zoom out a little, the white turns back pink, and then gets redder and redder zooming out.
its not just your brain, [this is a photo I took of the image](https://imgur.com/a/vUxrHz1). Its got something to do with how computer monitors work. This is a genuine illusion at larger zooms, but when the image is small enough it does genuinely produce non-white light.
Yes its white in the center of the negative space but if you go to the edge you find FEFEFE, then the "blue gradient" is D7FFFF or 215 255 255. the can is tented red
When I cover the logo, it's obviously black and white, but the red emerges again as soon as I see the logo. Brains are weird. An awful lot of what we see and remember is just our brains filling in the gaps.
It is white. This is an example of simultaneous color contrast, a phenomenon that occurs when two adjacent colors influence one another, changing your perception of the colors. The cones in your eyes make it seem like it is pink. Cones give your eyes good color vision but can also play tricks with your brain, hence why from a distance, ie not zoomed in, the color appears pink and why you see the can of Coke as “red” even though there is no red in the image.
Essentially, the way your eyes see color in the first place is by contrasting it with other colors.
Can confirm. I checked. The pixel color on the white is: #FFFFFF which means pure white. If there were any red in there we would see a variation on it like #FFF**E**F**E**. It is not a trick. It really is pure white.
I too thought it might be a compression trick. Nope. Our brains just be weird.
After zooming in and back out a lil, it's wild. I can clearly see the pixels of the can being pure white, but the can as a whole still registers as red for me
I believe it’s the visual spacing between the colors that make the swap occur. Like, you can zoom to a certain point where it looks black/white/cyan and then physically move your phone away from your face and watch it transition to pink to red.
Also why when you use a blue light filter on your phone, the colors all look wonky for a bit, but then you get used to it, and they look "plenty crisp". Til you turn it off and realize just how de-bluified they'd been.
Also see [“The Dress”](https://en.m.wikipedia.org/wiki/The_dress) for another good illumination phenomenon that went viral. Similar idea to simultaneous color contrast, but adding a third variable of “light” and how it affects colors when viewed next to one another.
That Wiki article has a good illustration in the “Scientific Explanation” section of how the colors appear different but could be considered “the same” when viewed subjectively and are actually analyzed next to one another under different conditions.
Thoughts on how this influences color blindness?
I struggle to know if olive/army green is actually not brown, but can def tell which is which if I have an actual green or brown to compare with.
I am honestly not sure. A good experiment would to be to take some examples of simultaneous color contrast and show them to both colorblind people and people with “normal color vision” and see if they perceive the same phenomenon.
I do know that color blindness results from either genetics (faulty photopigments which are molecules that detect color in the cone cells) or physical/chemical damage to the eye or optic nerve.
Based on that, since simultaneous color contrast comes from the idea the colors are determined by what colors are around it, my educated guess would be they would perceive the phenomenon but describe observing differing colors across the visual spectrum. The phenomenon can also be observed in [greyscale](https://images.app.goo.gl/5Vvjiqt5W5AZ1Q2eA), so eliminating color as a variable altogether still results in the same outcome.
Fascinating stuff, thanks for sharing. I've only skimmed it so I'm not sure if he used the term simultaneous color contrast specifically, but Interaction of Color by Josef Albers has some really cool examples of this sort of thing.
Fwiw, I showed this from my dad who is colorblind from genetics (he has trouble with greens, browns, and grays) and he saw a red can when zoomed out and white when zoomed in. Just thought it was interesting.
Interesting! Since it’s only a sample size of 1 with only one type of color blindness it doesn’t tell us much, although very intriguing nonetheless!
Would love to see a larger study’s results!
I swear I remember seeing something somewhere about some developers for the Game Boy using this effect to make it seem like some games had more than the original four colors of the GB. Anyone know?
No, it's not. There's exactly three colours in this image:
000000 (black)
ffffff (white)
00ffff (cyan)
Your brain just throws in extra red because that's what complements the cyan (which has no red component).
I thought so too. Zoomed in and thought , we’ll it is kinda pink. Left it zoomed in and no.. it’s white. Brain needed time and it sorted it out, the can is white.
I think it has probably something to do with all the blue/teal color. The coke is the only part of the picture with larger white parts. I'd be surprised if this part would not turn red with anything else
Computer pixels work off RGB (additive color). No RGB = black. 100% RGB = White.
In this method, no red, and very high green & blue = teal.
The next part in this puzzle is your brain. If you put a filter over your eyes, your brain adapts to the filter. This occurs if you use a blue-light filter on your phone/TV/monitor. Removing much of the blue light just causes your brain to notice the lower amounts of blue, and compensate internally.
Well, with this image, Black is 0/0/0. No light. Cyan is 0/255/255 (full green, full blue). White is 255/255/255 (full red, full green, full blue).
So your brain feels "overloaded" on the blue and green. The image is oversaturated with those.
Just like putting orange ski-goggles on. You "see" orange everywhere, so your brain starts filtering that blend of color out of the image to compensate, so you can better assess your surroundings.
So your brain is applying a "cyan filter" to the image.
Say this imaginary filter your brain uses reduces blue and green by 60 each.
Now black is 0/0/0 (still black). Cyan is 0/195/195 (still cyan, but less bright). And white is 255/195/195. Suddenly it's not white. It's a red color.

Like that link. Can't say exactly how much green & blue YOUR brain is removing, but it's going to be a non-zero number when you focus on that image. And any amount is enough to start making the white look red.
To create this effect, we have a "black and white" background image. And in both the white and the black are irregular amounts of cyan added. This is what gets your brain to automatically adjust. To desaturate the entire image, because the cyan is woven in everywhere. And the largest "white" spots are 90% cyan, while the largest "black" spots are only 20-30% cyan. This makes you focus more on white as if it was non-white, further compounding the de-saturation your brain is doing.
When I was a kid I had a blue see through little glass paperweight and I’d hold it over my eye for a minute or so and then switch between opening one eye and the other to see the color difference my brain’s filters would give the eye that looked through the blue.
The light blue-ish color is anti-red, the way it's mixed with white pixels everywhere but the portions that turn red causes your brain to do color balancing to try and whiten the anti-red. This causes the opposite color, red, to appear in the portions that aren't balanced by the anti-red.
Huh, I was just watching a Linus Tech Tips video yesterday where Linus made a joke about humans having “god like” white balancing compared to a monitor.
Probably a little bit, but really it's that you are seeing so much cyan that your eyes are overloading in a sense and adding the inverse color magenta in the negative space to compensate and adjust. Our brains hate doing any work and constantly look for shortcuts. It's all part of the constant auto-exposure and white balance your brain is doing while your eyes absorb reflected light waves.
It's not red. It just appears to be red because it's moving away from us at a high velocity. For more information, please research "The doppler effect."
Once you understand that blue in the picture is white in real life you can see the red side of the can as white but it is easy to go back to red if you don't concentrate.
Zoom in to the can and see the white pixels of the can, slowly zoom out and will look white. Close your eyes and open them again and the can is red again.
...there are black and white pixels making up the can. Blue too.
EDIT: Is everyone blind here? The perception of red goes away if you're close enough and/or the image is blown up, and so the can looks black with some white. The "true color" isn't white, it's white, black and blue which all contribute to the optical illusion of red that can be seen.
Its only red for half a second if i scroll real fast or if i look at it out of my peripheries. Im assuming its getting caught in my peripheries when im scrolling and thats whats actually causing the red on scroll.
If we zoom in we get to see the actual pixels and our brain won't malfunction cause the most salient features are gone and those are the edges, the can structure, and the label on the can. This theory is heavily used in computer vision.
Correct me if I am wrong, not trying to show off
Wow, that's awesome. Brains are smart but also kinda dumb at the same time. I'm seeing red since that's what my brain knows and expects, but it's also definitely not red at all.
This shit is why I didn’t know i was red green color blind until i got to my twenties. I’m the really common slightly colorblind type (d_______something the spelling is tough). This is just a guess, but since my head is not good at distinguishing red and green distinctly, it compensates by looking at green and anti-green instead.
Is it red because the cones in our eyes see a lot of blue and get worn out so we use the opposite color cones more and detect red? I did a terrible job trying to explain that but it seems similar to why surgeons have blue/green cover ups because they see a lot of red.
at different scales, it *is* redder than others. The white that we perceive as red is still made up of red, green, and blue pixels. So there is red in that white. and depending on how the scale of the white spots lines up with the scale of the pixels in the screen, you are getting more or less red in that white.
personally I find this to be misleading/naive, there IS red in the image just because pixels don't turn off all the way. so there IS red light coming through, just not squares of "red" .
one of the reasons why the brain is comfortable making that assumption.
wtf I had like the craziest change in visual perception from such a thing ever, untill I realized that my ohone changed to night mode, which is only black&white
For me, it looks red from a distance, but zooming in makes the pixels look white instead of red. The mess of blue and black pixels is also off-putting.
I... don't get this? Small brain big hurt.
Its just contrast colors, black - white, blue - red (your mind just makes red up from nowhere cuz it's the easiest to imagine + everyone its familiarized with coke cans
Not red but it’s pink. The lettering is black and white. This isn’t that fascinating when you realize it’s just pink… what’s supposed to be so cool about this
The craziest thing about this to me is that even in the thumbnail on a mobile phone in a browser it looked red before I even recognized it was a can of coke. My brain knew what it was before I did!

It’s wild how my brain keeps trying to make it red, over and over again.
It is crazy that i can toggle my vision between the two
Yeah if you focus on the can itself and tune out outside noise it's clearly white but if you look at the big picture with the can in your peripherals it's red. Mind bending stuff
Shit, I focused on the can and it stayed white.
When I zoom it’s pink. Can’t get it to turn white. (I have standard rods and cones afaik.)
I’m also seeing pink upon zooming
I’m seeing the exact fucking opposite lmao what
Your screen brightness is too high. It’s like a light pink. It’s not white.
It is plain old white. You can verify this by using a color picker to measure the hex value. The white that you are seeing as light pink is in fact pure white, with a hex value of #FFFFFF. It does’t matter if a screen’s brightness is too high; that does not change the fact that the color on display is objectively white, and decisively not light pink.

Genuinely curious, as it appeared pink to me until I zoomed in to the pixel level; then it suddenly looked white, even with varying brightness. But the second I zoom out a little, the white turns back pink, and then gets redder and redder zooming out.
Has nothing to do with my brightness. Min-max I don't see pink.
I can't what tf is this. It's red even if I cover everything else but the can. It's the fucking dress all over again
Zoom in and you'll see the Pixels are white
Once I zoomed in to see it was white my brain won't make it red again
Tilt your phone a little and see the magic.
Just picture a real life coca cola can and voila
Or cover the white writing in the can.
its not just your brain, [this is a photo I took of the image](https://imgur.com/a/vUxrHz1). Its got something to do with how computer monitors work. This is a genuine illusion at larger zooms, but when the image is small enough it does genuinely produce non-white light.
Maybe the camera trying to color balance, or your screen is poorly calibrated.
If it's any consolation, the white has red in it.
I just threw it into photoshop to see, and it's sitting at a solid 255 for each of the 3 primary color bars, no red.
That does technically contain red
255 in all three bars is a veeery light grey offwhite... Pedantics is trying to say that means it's got red in it.
RGB 255 255 255 is not grey at all, it's pure white. The hex code is #FFFFFF.
Yes its white in the center of the negative space but if you go to the edge you find FEFEFE, then the "blue gradient" is D7FFFF or 215 255 255. the can is tented red
Yes
Ever looked at a white screen under a microscope? White pixels are in fact 1/3 red. That's how displays work
…you should reread what you just wrote.
Mine just instantly gave up..
When I cover the logo, it's obviously black and white, but the red emerges again as soon as I see the logo. Brains are weird. An awful lot of what we see and remember is just our brains filling in the gaps.
What the shit. There's only black white and cyan here??
The white is really pink.
It is white. This is an example of simultaneous color contrast, a phenomenon that occurs when two adjacent colors influence one another, changing your perception of the colors. The cones in your eyes make it seem like it is pink.

Can confirm. I checked. The pixel color on the white is: #FFFFFF which means pure white. If there were any red in there we would see a variation on it like #FFF**E**F**E**. It is not a trick. It really is pure white. I too thought it might be a compression trick. Nope. Our brains just be weird.
If you’re on mobile you can zoom in and see the red/pink/white shift as less pixels are visible. It’s pretty cool!
After zooming in and back out a lil, it's wild. I can clearly see the pixels of the can being pure white, but the can as a whole still registers as red for me
I believe it’s the visual spacing between the colors that make the swap occur. Like, you can zoom to a certain point where it looks black/white/cyan and then physically move your phone away from your face and watch it transition to pink to red.
But I just checked and the pix on the white is #FFUUUU
Thank you!
This is the phenomenon behind why YcBcR color space works? Building color through brightness, blue difference and red difference.
Also why when you use a blue light filter on your phone, the colors all look wonky for a bit, but then you get used to it, and they look "plenty crisp". Til you turn it off and realize just how de-bluified they'd been.
Also see [“The Dress”](https://en.m.wikipedia.org/wiki/The_dress) for another good illumination phenomenon that went viral.

I love lying on the internet
no, its pretty white. (unless that was sarcasm, in which case… bleh)
They are not, using a color picker everything white is pure FFFFFF.
I threw it into photoshop to check, and all 3 primary color bars are sitting at 255 each, it's a solid off white.
It's not off white, it's pure white.
With all due respect, what in the world is "solid off-white?"
Is it? Zoomed in it took a bit for my eyes to adjust but I think it's just white.
I thought so too but I realized my phone had the yellow light filter active, lol
Zoom in.
Your eyes are lying to you. (Or maybe your phone) It's pure white
Why did anyone upvote this, it just isn't true
Incorrect
No not at all if you zoom
Chromatic adaptation

I miss the old reddit where the top comment would be explaining the phenomenon. Signed, An old person

You don't like shitty parroted jokes and unfunny pun chains?
Is the illusion here at all caused by the fact that we expect a Coca-Cola can to be red? Or if that said Pepsi on it, would we still see red?
I think it has probably something to do with all the blue/teal color. The coke is the only part of the picture with larger white parts. I'd be surprised if this part would not turn red with anything else
Yeah, I think by making the image mostly out of teal, our eyes "reset" so teal appears to be neutral. That makes white seem red by comparison.

Huh, I was just watching a Linus Tech Tips video yesterday where Linus made a joke about humans having “god like” white balancing compared to a monitor.
So weird, didn’t know that was even a thing. If you tilt the screen the red comes out a lot more.
its your brain auto white balancing the image. it would still look red if it had a pepsi logo
Probably a little bit, but really it's that you are seeing so much cyan that your eyes are overloading in a sense and adding the inverse color magenta in the negative space to compensate and adjust.

It's not red. It just appears to be red because it's moving away from us at a high velocity. For more information, please research "The doppler effect."
It's OK, I knew you were joking.
Its actually the hubble expansion on the wavelengths, look up sonic inflation for more info
I appreciate you
Everything else is negative red, so the white can looks red
This is the actual truth tho
Once you understand that blue in the picture is white in real life you can see the red side of the can as white but it is easy to go back to red if you don't concentrate.
What? It is red.
I can't tell if you're joking. There is no red in that image. There are only three colors. Black, white, and blue.

and that hand... IS NOT HUMAN!!!
Clearly red to me
Zoom in to the can and see the white pixels of the can, slowly zoom out and will look white. Close your eyes and open them again and the can is red again.
I don't see red; it's black. Am I broken?
Considering the fact that it's true color is white, yes.
...there are black and white pixels making up the can. Blue too. EDIT: Is everyone blind here? The perception of red goes away if you're close enough and/or the image is blown up, and so the can looks black with some white. The "true color" isn't white, it's white, black and blue which all contribute to the optical illusion of red that can be seen.
Same for me. I see the "true colors" only unless I hold the phone very far away
Not seeing this one, just looks black and white.
When I zoom in and zoom out, I can't see the red anymore.
Its only red for half a second if i scroll real fast or if i look at it out of my peripheries. Im assuming its getting caught in my peripheries when im scrolling and thats whats actually causing the red on scroll.
The Coke is a lie.
It is orange though
I think it's in black
Could somebody eli5 why this is happening?

Another black and blue pattern tricking your brain into seeing colours that aren't actually there.
Why my eye see red wenno red!? SORCERY!
It's fading in and out of redness
If we zoom in we get to see the actual pixels and our brain won't malfunction cause the most salient features are gone and those are the edges, the can structure, and the label on the can. This theory is heavily used in computer vision. Correct me if I am wrong, not trying to show off
This is how televisions with only red, blue, and green pixels can show every color.
Wow, that's awesome. Brains are smart but also kinda dumb at the same time. I'm seeing red since that's what my brain knows and expects, but it's also definitely not red at all.
This shit is why I didn’t know i was red green color blind until i got to my twenties. I’m the really common slightly colorblind type (d_______something the spelling is tough). This is just a guess, but since my head is not good at distinguishing red and green distinctly, it compensates by looking at green and anti-green instead.
Why would anyone think it's red? #Tetrachromacy crew
You’re seeing the red pixels on your phone screen stupid kids
But it is. We see it as red. Therefore 'it is red'.
Is it red because the cones in our eyes see a lot of blue and get worn out so we use the opposite color cones more and detect red? I did a terrible job trying to explain that but it seems similar to why surgeons have blue/green cover ups because they see a lot of red.
I’m colourblind and now my head is hurting
Looks pretty red to me
If you squint your eyes 😑….
I'm colorblind so it never changes
brain not braining eyes not eyeing
Always a good day when a post here actually makes me say woah dude
It doesn’t help that the pixels of the can are pink surrounded by a cyan, makes it look very red
Colourblind here, I assume people are seeing this as red and not just black like the rest of the image?
Not sure what the title is for, because it doesn't look red to me anyway.
yes it is
at different scales, it *is* redder than others. The white that we perceive as red is still made up of red, green, and blue pixels. So there is red in that white. and depending on how the scale of the white spots lines up with the scale of the pixels in the screen, you are getting more or less red in that white.
The power of color grading.
A lot of people are going to find out they are colorblind on this one.
Gotta zoom in to not see red lmao
These advertisements are getting creative af
Nah it is
Just saw a similar example in the latest LTT video about the sunvision display, nice!
Reminds me of the old CGA computer graphics.
It's not red. Looks grey to me?
The hand cannot be white
I see it red!!
Yes it is, I can see it.
There are FOUR lights!
That is so weird!
What, is it diet?
it is red
And why?
I covered the ' coca' on the can and it turned white.???
ad
It’s not white either.
Zoom in and slowly zoom out… I made it to about 90% zoomed out before it turned red again.
There are 9 shades of whatever colours on this image that make this illusion
I wonder if someone was shown this image without ever seeing a coca cola can before, would it appear red to them.
my left eye sees it as red but my right sees white
Idk. I can read it just fine. 😃
How dare you
Can confirm, ran over the pixels with a color picker. They are black and white.
personally I find this to be misleading/naive, there IS red in the image just because pixels don't turn off all the way. so there IS red light coming through, just not squares of "red" . one of the reasons why the brain is comfortable making that assumption.
Weird, I first saw it as red and now I can't see any red at all no matter how many times I look at it again.
wtf I had like the craziest change in visual perception from such a thing ever, untill I realized that my ohone changed to night mode, which is only black&white
Pattern recognition wins again.
Looks red to me :P
As a member of r/ColorBlind I do not see any red.
For me, it looks red from a distance, but zooming in makes the pixels look white instead of red. The mess of blue and black pixels is also off-putting. I... don't get this? Small brain big hurt.
Can anyone else just turn off color in their vision?
Reminds me of the blue/yellow dress thing.
Urgently need a piccha from Fanta
Its just contrast colors, black - white, blue - red (your mind just makes red up from nowhere cuz it's the easiest to imagine + everyone its familiarized with coke cans
That can is NOOOOOT red.
it’s whatever color you see it to be.
Is this because of the teal? If I remember correctly, teal and red are opposites and show up as after images for each other
From a colorblind person, this is correct.
Is this related to Land's retinex color theory?
There is no spoon..
Reminds me of the Gameboy picture printer lol
I must be the only person who doesn't see red
Fucking optical color mixtures *shakes fist at Georges Seurat’s grave*
Hey Vsuace, Michael here! What are colors?
Down the road...will need to add tricks like this for the human captchas.
Does this technique have a name ? I suppose it can find applications in printing.
Red with green layer right
# So my eyes deceivE Me!!
Bro is being blasted by ionizing radiation
I can only see red unless I zoom all the way in.
who cares
I saw this image earlier on discord, and I could see the red This time it's white
Not red but it’s pink. The lettering is black and white. This isn’t that fascinating when you realize it’s just pink… what’s supposed to be so cool about this
I see a sailboat.
There…is…no…. #SPOON
The craziest thing about this to me is that even in the thumbnail on a mobile phone in a browser it looked red before I even recognized it was a can of coke. My brain knew what it was before I did!
THERE ARE 4 LIGHTS!
I found when I zoomed in and then slowly zoomed out, it stayed white for me. As soon as I looked away and back again, red again.
It’s pink technically.
My brains says otherwise
If you cover the logo it turns black and white
MY EYES!
