how to change blackbox background color?

["Benjamin F. Zhou" <zhoub@fisci.com>]

Hi,

 I just replaced olvwm with blackbox as my default WM..

 I like everything it provides except the background screen color. I tried to
screen-edit it,  but there is no such option there.

 Is there a way to change it? the wired background makes my eyes pain.

 thanks a lot !

 Ben
