Colors do not just magically flip, not outside of gradient variances and medical conditions. This is absurd bs just like this whole "viral" debate where people were arguing over how camera captured the stupid dress. The camera captured it in that stupid way to look entirely different, not my eyes. Even color picker in image editor proves that on the photo of the dress, the gold is gold and the white is so far washed out blue that can easily be declared white. Are you going to claim mathematical tool has wrong perception of color too?
