> The first thing that struck me, as a software engineer, is that four colors is not very many. I really like the visualization. It's a happy medium between something like UML and something that's actually useful, and creates useful constraints around communication channels between classes. I'm sure there's some design pattern that breaks the rule, but overall trying to force a "4 color" programming pattern seems like it can't do anything but help.
