"humans can perceive reality differently", yea, that's true, but the thing with the dress picture is that it's so obvious that there is a bright white light, that people doesn't see it, like, never in it's entire life have ever use a flashlight or somelight like that and see how shuch kind of light can get colors brighter. We have the sun, damnit. If the light in the picture were more blue or purple like, the dress would be more darker, BUT! if the dress were actually white and golden/yellow,with the light said before, would be getting the same result, but it's not the case.

"humans can perceive reality differently", yea, but this is not of one cases
