This is more entertainment than debate so keep it friendly. I would think by now some of you have heard about people seeing different colors in a blue and black dress (according to some sources those are the actual dress colors.) A discussion of the matter. Part of the issue is the optical illusion of lighting, our brains correct colors and tell us what they should be, not what they are. The checkerboard illusion easily demonstrates how perception affects what colors we are sure we see. A and B are the same color. Some say it is the lighting tricking us like the checkerboard, some say it is different individual's color vision, and Bill Nye suggested light scatter had something to do with but that makes no sense because we should all be affected by the same light scatter. I see a slight blue tint to the white and gold trim. It surprises me some people see black instead of gold. I've tried isolating the black to see if I see a different color like you do with the checkerboard to see the squares are the same color, but I still don't see black. I'd love to see the actual dress in person with the same lighting as is in the image.
