Colors in screen graphics: `crt_palette' gives the default color palette in screen graphics. If this parameter is missing, the original Survo palette is selected. Other alternatives are crt_palette=<file> where <file> is a palette file name with default extension .PAL and path <Survo>\U\SYS . Example: crt_palette=VGAGRAY.PAL (gives shades of gray on the VGA screen).
