The colors are typical, tried and true, terminal colors, that have been in existence since ANSI became the standard. If they don't work for you, I recommend changing the color palette of your client.
As for making them customizable, I didn't do this with nodes because I want nodes to be presented as the author intended, colors, and all. Otherwise, colors are kind of meaningless, no?
