I wanted the functionality so that something like this could be scripted and added to servers:

I feel the additions, while welcomed, aren't enough choice. Too many whites, not enough variation in colors, etc. You could add functionality so that scripters could add these colors without having to use names, and having those names added as a fallback for people who (for whatever reason) like to use commands. I don't know, I just feel this is a waste as it is.
