My guess is the "Coca Cola" label tricks your mind into adding the red color?



Curious minds would like to know the reason for this optical illusion.

Color theory is the answer moreso than branding. Red and cyan are complementary colors, and the image is filled with so much cyan that when you see the area that's devoid of cyan, your brain interprets it as red.

For me, it's clearly black and white when viewed straight-on but seems red in my peripheral vision. I saw someone in the thread try to explain that the "white" areas were actually red-tinted but I did not find this to be the case in my own analysis.
