comments-background? (maibe a stupid question..)

Hello everybody!

maibe a stupid question, but its really bugging me and i cant find how to resolve it.

i changed to look of my blog a bit, changing the styles.css. i use a dark background, so i chose for a white font color. everything works fine, except that the comments are in a little white box, wich means you cant read the comments!

how can i change the font color for the comments? or how can i change the color of that comments box?

thanks alot in advance!!!
