The sky is much too gray and dark. I'm after a spring morning mist. What once appeared violet now looks murky and gray. I saw an excellent online video from the World Science Festival and sponsored by of the Alan Alta Flame Project. All About Color features 3 neuroscientists, one of whom is also a painter, explaining how the eye and brain process color. One of the lectures addresses how color is relevant to its surroundings. This is what happened to the once beautiful misty violet that became a murky gray once the green leaves pronounced themselves.
