[xmonad] ppVisible with 3 screens

Hi, I was using 2 screens with xmonad and xmobar. The settings ppCurrent = xmobarColor "#CC0000" "" . wrap "[" "]" , ppVisible = xmobarColor "#EE9A00" "" . wrap "[" "]" , ppTitle = shorten 80 , ppSep = " | </fc>" , ppHiddenNoWindows = xmobarColor "#AFAF87" "" , ppUrgent = xmobarColor "#EE9A00" "" . wrap "[" "]" worked good for 2 screens: The active workspace is red and the inactive is orange. But now, with 3 screens, there are 2 inactive workspaces and they both are orange. Is there a way to say: inactive on screen 0 = blue inactive on screen 1 = ornage inactive on screen 3 = green or something similar. Thanks for your help! Regards, Felix
