At the same time, it depends upon man's grade of evolution, his character, his nature - whether he is gross or fine - also upon his temperament - whether he has a practical nature or is dreamy, whether he loves the drama of life, or whether he is absorbed in the ordinary things of life. According to man's condition, his temperament and his evolution, color and sound affect him, and the proof of this is that man so often changes his fancy in regard to color. There is a time when he is so fond of red; there are times when he longs to see purple, or when he dreams of mauve. And then there comes a time when he takes a fancy to blue; he craves for yellow, for orange. There are some who like deep colors, others light colors. It all depends on their temperament and their grade of evolution.
