changing colors of menus to match wmaker

Hi I'm a GNUstep newbie, have been running WindowMaker
for a long time though (and love it).

I've just installed GWorkspace and Affiche on my Slackware
Linux box, have them running and I'm wondering if there is
a way to change the pull-down menus to match the menu colors 
I'm using in WindowMaker, haven't seen anything in the docs
or on the web about this. Thanks for any advice,
