But why?
Obviously it doesn't matter what color the pixels in the image are, but on how our brain percieves them. Do 70% of people not have enough experience with materials and lighting conditions to correctly determine the base color?
I guess as a game dev I have an unfair advantage. I'm always looking and watching how light affects a scene. It's something Ideal with almost daily so I guess I percieve the dress from that angle.
