I have met a bug with the colors customization.
This bug is with context menu when we right click on files or folders.
If I don't activate office 2003 style, the colors are displayed correctly. But if I activate office 2003 style, the background color is not displayed and I get a white background.
I precise that this happens only for the context menus on files and folders. All other context menu can be changed in customize mode.
I show you the screenshots...
