This isn't what i would call a typical exploit but a corpie has been told not to use this in public channels by a gm so i'm guessing it's not well known.
anyway this is how to get blue/turquoise writing which i would say looks better then white.
first put a / in the convo box then press ctrl b then type emote then whatever you want in blue
only thing is you end up with emote before whatever you type but blue is cool
