How to assign different color for each user?

Hi,

I just noticed that when I login to chat room through sparkweb the users’ color are all same color and only have 2 background white and light yellow. When user replied, it showed same color black.

Is there a way to configure the color on the Sparkweb? This is not happen if I connected through jabber client such as pidgin, psi etc.

I ma using Openfire 3.6.3 and Sparkweb 0.9.0

Thanks.
