I am not sure this will work the way most people expect when used in chat.
As the colouring is currently done on the sending client and not the rendering client (I know its awful).

Aside from that, there is already a mechanism to expose the theme colours etc to the frames, these values should also go into the css so that they can be used consistantly with the other colour values.
