WHAT THE FUCK.
I thought this was a troll thread and was about to photoshop the pic to put the two colors next to each other and make them the same color to troll people, BUT THEY ACTUALLY ARE.

What kind of sorcery is this?

McCollough Effect.

Be warned, this may be a permanent illusion.

"To obtain the effect, first look at a test image similar to that at top right. It should contain oppositely oriented gratings of lines, such as horizontal and vertical as shown here. Next, stare alternately at two induction images similar to the ones directly beneath the top image. One image should show one orientation of grating (here horizontal) with a colored background (red) and the other should show the other orientation of grating (here vertical) with a different, preferably oppositely colored background (green). Each image should be gazed at for several seconds at a time, and the two images should be gazed at for a total of several minutes for the effect to become visible. Stare approximately at the center of each image, allowing the eyes to move around a little. After several minutes, look back to the test image; the gratings should appear tinted by the opposite color to that of the induction gratings (i.e., horizontal should appear greenish and vertical pinkish)"

>> No.6467717

>>6467680
Dammit, you already beat me in mentioning it!

Anyway, just be careful if you try the illusion above. The effect can apparently last several months if you stare at it for 15 minutes or more. Who knows if it will be permanent for some people.

Ah! that one is cool!

i think i've figured that out. Since the white and yellow are closer the difference between the blue and white stands out before the yellow white gap does

>> No.6467780

>>6467756
"Their motion is exactly the same but the stark contrast of the lines and the light yellow and the dark blue makes them look desynchronized while in motion. Your brain has difficulty seeing the yellow edges against the white and the dark blue against the black.

The yellow appears to speed slow down as it enters the white lines, while the blue appears to slow down as it enters the black lines. In reality, it's all an optical illusion. Only when the squares get close to each other your brain realizes they are moving at the same speed."

From the gizmodo article where I stole it.
