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.
Can you do that and post it?
Grab your pitchforks gang. OP is selling us snake oil posts!!!
Now send this version (with the same unedited caption) to everyone.
Strange, I see the OP picture as red, but this one as black & white.
so it would appear red even if it was another can?
Huh, it shows up as black to me.
It’s curious that the thumbnail actually has red values for those pixels, making me think they’re cheating a bit with jpeg compression effects.
It’s not marketing, just colour theory. The same idea has been used by painters for ages.
It is when you use cova cola instead of, lolipop, santa, flag, flower or some other red object.
Nah, it’s still colour theory. Now it’s yellow, magic.
Jokes on you I zoomed in and out on the original and now the can appears white no matter what.
Its the second Coca Cola TM post ive seen since I joined lemmy.
The other one was yesterday.
This site has no protection against marketing aside from moderator action (and in this case OP is a mod). I’m not certain OP chose a coke can for that image or whether this was simply the first version of that illusion that OP has seen
I wonder if prolific posters are approached by advertisers. Is Lemmy big enough for them to bother?
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.
Yeah, there seems to be a lot more going on here than just marketing. If you mask the logo, the red still works. I believe it has to do with the combinations of white/black, white/cyan, black/cyan and the relative size of the blocks to produce a red hue through complimentary color persistence or whatever it’s called.
Hand doesn’t look red tho
Brain uses expectations to decide what to fill perception with. you don’t expect hands to be the same red tone as cola cans.
Nonsense. My phone screen uses red, green, and blue to make up each pixel. The white pixels have their red component all the way at full brightness. Therefore there is a lot of red in the picture.
You could also see this by opening up the image and looking at the red channel which would not be completely black.
I just tried printing this image but it says my magenta is too low 🤔
Texts on computers is made this way, so use a magnifying glass on black white text in a word document (for example) and you’ll see lots of colors. zoom in using the computer and you will still just see black/white.
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?
I’m red green colorblind as well. I just see the background as white or a very light shade of grey. Someone else has made a post with a yellow can and in that one I see the background as yellow (which is basically the same as green to me, I have very little r in my rgb), especially the right side of the can.
Same here. Those colour fanatics are fantasising again I suppose.
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.
If I zoom in just a bit it’s white, turns instantly red at some point of zooming out.
The tipping point is wild
Your mind compensates for the teal which makes the white look red.
It’s actually all just white light at different wavelengths, which tricks your brain into seeing different “colours”.
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”.
Making your brain do exactly what it’s supposed to do is a weird way is “tricking” it.
Still red with no logo.
White light has red in it. Cyan does not. We fatigue blue and green cones everywhere but the white can, and we only stimulate the red cones on the white can. The result is it looks red.
Thank you. I thought this was going to be like the dress.
The white and gold dress, you mean?
Exactly
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)
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?
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.
At the size it is on my phone screen it looks very red. Zooming in makes it look like the red switches to white.
Someone did a color swap and the can looks blue when the cyan pixels are instead yellow
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.
I have myopia so if I place the phone far from my face I can’t see that it is even a can… I still see a little bit of a red area there.
Here is an 8 minute video that goes into more depth on how this works. https://www.youtube.com/watch?v=0FjjJha7HMI
I’m colorblind this trick doesn’t work with me
This is one of those actually cool optical illusions
The “white” is actually very pale pink. At least on my phone screen
When I zoom in on my phone, it’s absolutely white
Must be hardware variant
I had that issue on an old phone, could very well be hardware variance.
Might have a blue light filter on your phone or something
That tends to make your phone screen look yellow/orange. Pink is a different thing.
My phone was old when i got it a couple years ago so yeah
My phone makes it pink too. But you can still see some effective difference when zooming in/out.
