Just a silly anecdote but a friend of mine had a room painted "this exact same pearl grey" used in another room. After having it grey, he realized it did not look grey but blue (I know why it was, because the only window of that room got the light reflected from a large bronze-green roof). He had it repainted a different tint. That was amazing.
