Red is complimentary to cyan.
If the cyan were switched with yellow, the can would appear blue.
Also, it’s not our brains creating the red, it’s our eyes. They get exhausted of seeing the cyan and replace it with red.

It depends on the size you are viewing it at. This works well on small screens but less well on large screens

So if the can shown wasn’t Coke, but Sprite, it would still appear red? Or is it a mix of both? The eyes are confused and the brain fills in? Like when seeing pink as mentioned elsewhere.
- stebo ( @stebo02@lemmy.dbzer0.com ) English4•3 months ago
Your brain isn’t filling in anything. Your blue and green receptors get oversaturated by the cyan, which causes your red receptors to be more sensitive to the white light than the other two, which is why it appears red. The effect happens in your eye, not in your brain.

It’s not marketing, just colour theory. The same idea has been used by painters for ages.
- srecko ( @srecko@lemm.ee ) English11•3 months ago
It is when you use cova cola instead of, lolipop, santa, flag, flower or some other red object.

Why is my brain making the train stripes red? I don’t know what color they normally are, which I assumed was the mechanism behind the coke can illusion.
- Nachorella ( @Nachorella@lemmy.sdf.org ) English13•3 months ago
Nah, it’s still colour theory. Now it’s yellow, magic.
- smeg ( @smeg@feddit.uk ) English49•3 months ago
Oh weird, I assume this is just because the white is relatively red compared to the cyan, right? As in if you took any image and coloured it in the same way then it would also look red.
- RinseDrizzle ( @RinseDrizzle@midwest.social ) English4•3 months ago
Hand doesn’t look red tho

Jokes on you, I’m moderately red green colorblind so I wouldn’t realize it if there was red present

Do you see the Coke can as a different color from the background?
- 🇰 🌀 🇱 🇦 🇳 🇦 🇰 ℹ️ ( @Kolanaki@yiffit.net ) English14•3 months ago
That’s wild as fuck. If I actually concentrate on the “red” it becomes white and then only becomes red again if I look away for a moment.
- widw ( @widw@ani.social ) English14•3 months ago
I think there’s something more going on here than just “marketing”. Because if you look at the tiny thumbnail in the OP it’s very clearly red, and you can even load that thumbnail into an image editor and zoom in to see slightly reddish pixels.
So something happens when scaling this image that actually results in a red hue, and I don’t think my computers image scaling algorithms are also falling for “marketing”. I would guess it’s actually some kind of sub-pixel trick that makes it seem like there’s colors there which aren’t, and that’s why the image scaling algorithms also reveal the same colors you see.

- underwire212 ( @underwire212@lemm.ee ) English13•3 months ago
Is this because our brains have been programmed to see Coca Cola can as red? Or does it have something to do with the way the black and white boxes are organized? (I.e. if it were a sprite can, it would still be red)
- flamingo_pinyata ( @flamingo_pinyata@sopuli.xyz ) English17•3 months ago
I think it’s a bit of both. The light blue color used is so called “complement color”, meaning it’s exactly the opposite on the color wheel to the Coca Cola red. Black and white pattern suggests to our brain to play with contrast. And of course we all know Coca Cola from all the marketing.
Btw, After staring at it for a while I can kinda switch between red and white at will. Anyone else?
- tiramichu ( @tiramichu@lemm.ee ) English5•3 months ago
Interesting :) And yes, for me it also became easy to switch once I was aware of the truth of what I was looking at.
If you look directly at the can you can see it as white, but if you look elsewhere and the can is only in your peripheral vision it seems to always be interpreted as red.
- snooggums ( @snooggums@midwest.social ) English3•3 months ago
At the size it is on my phone screen it looks very red. Zooming in makes it look like the red switches to white.
- mexicancartel ( @mexicancartel@lemmy.dbzer0.com ) English12•3 months ago
The cyan is the one playing the trick. I can see the black and white nature without zooming when focusing on the logo or something. Sometimes it randomly changes from b/w to red
- Swedneck ( @Swedneck@discuss.tchncs.de ) English12•3 months ago
It’s effectively your brain doing automatic white balance, it sees everything being tinted cyan so it just sorta subtracts cyan from the area, which results in white being reddish
you can do this physically (by tiring out the colour-sensing cells in your eyes) if you stare at a colour for about 30 seconds then quickly look at a white surface, you should see the inverse of the first colour.
- Pulptastic ( @Pulptastic@midwest.social ) English13•3 months ago
Your mind compensates for the teal which makes the white look red.
- GTG3000 ( @GTG3000@programming.dev ) English1•3 months ago
It makes gray look red because it’s similar luminosity. White still looks white.
- stebo ( @stebo02@lemmy.dbzer0.com ) English1•3 months ago
then why are the other parts still white
- MBM ( @MBM@lemmings.world ) English1•3 months ago
The image has teal-black parts and white-black parts, the white-black parts look like they’re red-black
- NigelFrobisher ( @NigelFrobisher@aussie.zone ) English11•3 months ago
It’s actually all just white light at different wavelengths, which tricks your brain into seeing different “colours”.
- vonbaronhans ( @vonbaronhans@midwest.social ) English11•3 months ago
White light is the combination of all those wavelengths. It is only the combination that makes it “white” in exactly the same way that a smaller range of wavelengths are “red” or “blue”.
- lolcatnip ( @lolcatnip@reddthat.com ) English2•3 months ago
Making your brain do exactly what it’s supposed to do is a weird way is “tricking” it.
- stebo ( @stebo02@lemmy.dbzer0.com ) English1•3 months ago
no actually it’s white light with different phase shifts and because the earth is flat, the surface temperature of the sun tricks your brain into thinking it is red
- warm ( @warm@kbin.earth ) 10•3 months ago
I only see the red when its small, in the thumbnail its red, but when I open the image its very black and white.
The white has more red in it than green and blue, so that’s probably the cause of the illusion.

indeed. I hate ads. Even more forced ads of liquid sugar. Would have loved to see that red tree if only to prove that its not about the familiarity to the item.
- ladel ( @ladel@feddit.uk ) English9•3 months ago
If you zoom in to see that it’s black and white, and then zoom back out again, it stays black and white. But if you look away for a bit to forget, maybe change the angle you’re looking at it, it turns red again.
- snooggums ( @snooggums@midwest.social ) English5•3 months ago
For me zooming out changes it back to red.
- FiniteBanjo ( @FiniteBanjo@lemmy.today ) English8•3 months ago
When its small thumbnail I can see it but when I look at the full size image I appear to be able to turn the effect off at will.
