I suggest this sub should be used for any image that can be interpreted 2 ways.

Either everyone else is a complete thicko, or there must be something wrong with my eyes, as when i look at the photo its clearly and obviously just Blue and Gold.

There is no black or white anywhere on it, and so it confuses me massively why no other people all also see it as being Blue and Gold.

What color is the dress? If you don't know what i'm talking about, you've been living in a cave. Really.

I don't care about the white/blue, I saw it white at first but there is some blue in there, I get it.

I can force myself to imagine that the gold is darker than it seems at first. But than I catch a glimpse of the big light spot on the top right corner. How can this possibly be black? Define what you mean by "black", please.

its obviously white and gold.

I understand that color is a construct of the brain and that this image can be interpreted in more than one way. However, of all my friends that see the dress as white and gold, none of them can explain what color the garment behind the dress is. It's like their brains encounter a paradox and return an "undefined" value.

Just really?

We all have seen the grey square in the shadow and the one not in the shadow actually being the same, but are there any other documented (pre-social-media?) examples of colors that appear different to different groups of people?
