Change the color and looks of desktop icons fonts
To change the color of the fonts on the desktop icons:
Right click on a icon.
From right click menu select:
Rox-filer->options->pinboard->appearance
Font color:
Change the foreground color to what you like.
Select OK when you are done.
Other options:
Font shadow and color of the shadow.
Use a custom font
Note:
Background option is not active.
Background is controlled by the desktop wallpaper program. (JWM Desk Manager->Desktop->Background)
However, the wallpaper program is actually changing the background image used by the pinboard.
If you right click on any desktop icon, select "Backdrop" and clear the image. Should give you a monochrome background with all icons intact. Then right click again and select ROX-Filer -> Options -> Pinboard -> Background to change the background color.
