Yeah, I've annoyed my players with using rainbows of colors for text already, particularly in the "All Outta Bubblegum" game, where I used purple, brown, and orange a lot. I tried to avoid yellow, as it didn't show up very well.

You can actually put in hex colors as well! I'll probably add in something like ooc="text" where text is the same color options color="text" takes.
Ooh, I like it!
