Okay, that's win.

I really thought this had more than four colors at first. That's a very cool effect you have going on.

 skulls and rainbows, the two coolest things ever in one single picture. YEEAH!

You've got my vote!

awesome ! Nyan skulls ?

this is awesome

Thanks everyone! :)

@ Manupix  I did think about different dithering patterns but decided to keep the dithering uniform. If the image was bigger then I would have. :)

Brilliant use of optical illusion to create more colors than there are.

I'd like to see more interesting dithering patterns in some places.

very good. What I like best about this is you used bright vivid colors and werent scared to!

You win =P

woah! nice job getting creative with those colors
