Admin color text sounds like great idea.

But for general chit-chat I can not do any promises, when time permits in future we might implement something in this area.

Original design of blastchat was for fast, easy to read chat (at least that's what we are trying to offer our customers).

More colors are distracting (why do you think that your document editors do not show each line with different color? )

It will be very nice if the admin /moderator of the chat will be able to write in the chat in a unique color.... (like blue while everyone type lets say... black)
also, user will see what his/her wrote in one unique color (not just his name...)

stuff like that will boost my chat!
Thank you.
