Coca cola appears red when no red at all is used in whole image
- flexagoon 9mo agoThis is a great illusion, though I often see that people try to explain this (and a similar image of strawberries) as "our brain knows this object is supposed to be red so it fills in red", which is not what's happening - it's based on color contrast like many other optical illusions
- mediumsmart 9mo agoThe background on the can is a very light red. I know from painting murals that a light color close up looks darker from some distance.
