Well if you see blue or black, your retina cones are more high functioning which results in subtractive mixing. If you see gold and white then your eyes don't work well in dim lights so your retina rods see white, thus making them less light sensitive. This causes additive mixes. Also, if you see gold and white, try staring at it for a while and you might see blue and black.
It has to do with how good ur eyes pick up colours or something blue and black is the proper colour the owner of the dress has admitted it
Its depends on what side of the brain you use if you see blue and black you are right brained if you see gold and white you are left brained if you see something else you're color blind
I've seen it both ways... weird I can look at it and it's blue and black close it out for a few hours and look at it and it's gold and white
