How best to combine colours

[Malcolm Williamson]

The GRASS XDRIVER, including the modified one for use with 24-bit 
displays, only display 8-bit color (256 colors). Hence, all full color 
images will look lousy on the display. Note that ps.map inherently 
produces PostScript files with 24-bit color, so one solution is to 
produce a PostScript file and then _view_ it on a 24-bit display with 
Ghostview (freeware).
