Colors are unsigned int's (32 bit). The components are encoded RGBI where I is
an index, or , if that is 0, RGB are 8bit color components. To get the RGB
value from any color, use:
static void Fl::get_color (Fl_Color i, uchar &red, uchar &green, uchar
&blue)
Returns the RGB value(s) for the given FLTK color index.
and compare components
