Nah, I personally won't think it's a good idea. Chat is already a rainbow of colors, and I don't want it to get too crazy. The chat will just end up looking really ugly from the huge amount of colours that are in it. (I assume you mean to be able to change individual word colors, if i'm wrong please correct me...)
+1 for the ability to select the color that ults want to be able to use. Adding another color seems like a great idea to me, as long as it doesn't get too crazy...

I meant an option to change their default chat colour, not colours within each message, for example: /chatcolour red as opposed to /g &1 Hi &2 Guys! I can however, see where you're coming from, so perhaps a limited amount of colours that can be used, say 3 or 4?
