Sometimes you just feel so stupid. This is one of the times for me. When I first developed ChatColors, I tried to find a way to figure out what colors the channels already had, so I could just save that. I didn't manage to find a way and I still haven't, but I just found the event UPDATE_CHAT_COLOR that could help a lot.

My guess is that version 1.0 will contain the possibility to change color in the Blizzard UI and save it. I still find it useful to be able to save colors in the settings, so I don't have to set everything up for each character. That means I won't cut down ChatColors to nothing and just save the color on the event, but rather keep it as it is, even if it's perhaps does a bit more than needed.
