Not everyone sees the same color when they stare at this spinning disk.

The gif is called, “Benham’s disk“ "is named after the English toymaker Charles Benham, who in 1895 sold a top painted with the pattern shown. When the disk is spun, arcs of pale color, called Fechner colors or pattern-induced flicker colors (PIFCs), are visible at different places on the disk. Not everyone sees the same colors.”

“The phenomenon originates from neural activity in the retina and spatial interactions in the primary visual cortex, which plays a role in encoding low-level image features, such as edges and spatiotemporal frequency components.”

Fascinating how our brains work, I see a brown tan, what do you see? :D

Interesting, I saw a light green and my wife saw purple.
Note: remove your glasses, especially if they’re polarized.

…Black and white?

an epileptic fit.

I saw brown, and the friend I have over this week saw red.  Fascinating.

Also, I apologize for sharing the headache this gave me with all of my followers.  A small price to pay to learn about something nifty.

I actually see three colors a redish purple, then teal then a pale brownish yellow, then teal again and so on :|
