Changing font color in richselect

I am able to change the background-color via css style, but color statement is ignored – the control always displays black text. Any suggestions? thanks!

.redCol {font-weight:bold;background-color:rgb(255,200,200);color:rgb(0,100,0)}

try !important attribute

.redCol {
   font-weight:bold;
   background-color:rgb(255,200,200) !important;
   color:rgb(0,100,0) !important;
}

Thanks for the suggestion!

However, I managed to figure out to how to do this by looking through the documentation. There was a very clear example of how to achieve the needed.
