         *  - we can add up to 10 different colors: [0..9].
         *  - we need a link and a highlighted link colors.
         *  - not all colors will be fine with all backgrounds due transparent
         *    windows and widgets. So, I think it's better keep BrowserBox
         *    opaque (white background) by default.
