Colors DO EXIST, AND IS NOT ONLY PERCEPTION
WRONG, colors exist outside the brain. First of all, colors aren't formed in the brains, colors are formed in the EYES and PERCEIVED in the brain, And this has been proved over and over, COLORS ARE FORMED IN THE EYES (achromatopsia and colour blindness PROVES IT, retinal problems), so you are wrong. without colors existing objetively we would never see color first, the brain CANNOT create something from nothing. You are seeing the world (colors, shapes, etc) with your eyes and PERCEIVING it with your brains.
So, update this article, because It's totally WRONG. There are no doubts of color existing.
