      It is when you use cova cola instead of, lolipop, santa, flag, flower or some other red object.

    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.

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

    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.

    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)

      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

      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 only see red if I take my contacts out and hold my phone really far away, but then its all one blurry mess.

    Weird but if I focus my mind so to say it appears white but then if I relax then again red
