Just saw this cool thing on Tumblr, basically it's a .gif recreation of a phenomenon known as Benham's Top (or Benham's Disc). It's a pattern that, when spun, generates arcs of color on the disc. However, the cool thing is that there's a massive variation on who sees what color, so it's likely that two different people will not see the same colors.

The .gif is a bit seizure inducing, so I'm putting it in the spoiler tag. I see alternating arcs of black and gold. What colors do you see?

 

I see halves of black and white.

I honestly just see black and white with grey blurs. o.o I think for a little while I saw a kind of gold-green, but I can't seem to replicate it.

green, black, and white

I also saw this on tumblr! I see the same as you

Gold, Black, and White.Funny thing is, when Screecapping, it only shows Black and White.

goldish green

I see the circle spinning to the right, with black and white walls flashing around, with slight grey, brown and a tiny bit of green arcs in the white spaces.

black, red, and blue

If you didn't tell me you could see colors, id say black and white.

 

Now I'm just imagining small lines of colors lol

That's what makes it so cool! When it's motionless it's just a black and white pattern, but something about how our eyes perceive the motion causes the illusion of color,. The thing is that different people can see different colors, kinda like how two people can't see the same rainbow.

Black and white halves with a reddish tinge to them 

green,white,black,and gold

I just see black and white.

Yellow, Blue, and a bit of Brownish Red.  Cool!

 

And now the yellow looks green.

At first it was going really slow and I had no clue what gives, then it sped up and in addition to black and white, I started seeing grey and a sort of olive green color.

Aside from the blacks and whites, I think I saw orange and green...I think.  

Green, gold, and pink/red.

Arcs of black and white, and then, a few seconds later, it completely changed, I saw lines of orange and green
