How to change the font color in yahoo messenger from black to white: Instant Message under the Call button?

I want to change the font color of three fonts inside of an yahoo messenger skin:

1. The font color (from black (default) to white) in the Instant Message window, of the person with who you are talking with (under the Call button)

2. The font color of the text that apears in the very bottom of Instant Message window (xxx is typing a message) to white

3. The font color of the '; xxx is now online/offline'; window, also to white

I need the things above because i'm making a skin that has the background black, so the text in black can't be read.

I'm awaiting you're answers.How to change the font color in yahoo messenger from black to white: Instant Message under the Call button?
