The Color Of That Dress...
I am convinced that all the hubbub as to the various ways people see the colors of the dress going viral online is proof that any image we see is more subjective than we ever thought. Which begs the comment about art critiquing... Outside of pure technical suggestions, anyone with an opinion of how another's art looks is a purely subjective, and we should take much solace in that!
