Colors can affect emotions, but not everyone reacts in the same way.  Red and blue in this part of California are gang colors, so a Norteno and a Sureno would have opposite reactions.  Teams also have colors, so a Raider fan might be happy with black and a 49er fan happy with red.  A Sharks fan seeing teal might register disappointment that they keep losing.

I don't know what you mean by white making you feel clarity.  White can be a symbol of peace, or a symbol of surrender, or a color of death in some cultures.
