How to change then background of mocp

Hello everybody, I'm using gentoo linux and mocp, but I had a question:
1. On console, my mocp's background color is blue
2. On terminal(urxvt), my mocp's background color is yellow.

How to configure mocp background color?

Thanks all!!

I am very Sorry!!!

I had no search this site before send my question!

I had solved myself question

because i download source and compile, So man command can't find out mocp help page!

Suggest: "how to get mocp help page" append to FAQ page
