That's the hard part. What defines color similarity? This involves
color perception theory. We lose our ability to differentiate colors
as the brightness goes down. Can you tell #000002 from #020000?
Perhaps you should have a minimum brightness. Also, how many colors
can we reasonably distinguish? What if a node has 20 children? 50? 250?
