Default user color in chat

Perfect, thanks! Dunno how I didn’t think of looking at JS.
I’ve been doing a simple crc32 but this is much better.

Btw, just the last couple things I’m missing, if I don’t manage to find out myself - how are system messages represented in IRC, like subscriptions or slow mode/r2k? And how are admins/staff identified, by SPECIALUSER or MODE?
