There was some thought about color during What if Diaries this year. How color might be a story in itself. There were nine colors. Just sitting there feeling different from each other. Holding their ground. Then they began talking to each other. This caused them to become more sympathetic to each other. There is a tendency for one color to lean toward another. Learn from another. Share. Touch. Integrate. Become more. This is why there might be so many different kinds of colors.
Of course there is also a full spectrum of tendencies.
