mod_gk_js_members change black color to some other color

Hello All,

I am using mod_gk_js_members on musicity and I can not make it to change color. I try to change it with module class suffix set to " grunge5" " grunge4" " grunge3" and does not have effect still leaves me with black color. I also tried going to mod_gk_js_members css to find this black color to change and still can't find it. How to change these colors from black to something else? Where to go to change it.

Thanks!
