 This allows the user to specify his/her colour preferences for the screen.
 The numbers are IBM-PC Mode 3 colour attributes on DOS and OS/2.

 Colours are made up of a foreground colour, a background colour, a flash and
 a brightness value. Values are :-

        Black           0                       Flashing        1
        Blue            1                       Static          0
        Green           2
        Cyan            3
        Red             4
        Magenta         5
        Yellow          6                       Extra bright    1
        White           7                       Low brightness  0

 The complete colour is calculated as :-

        foreground_colour +
        background_colour * 16 +
        brightness * 8 +
        flashing * 128

 eg: bright yellow on red is 6 + (4 * 16) + (1 * 8) + (0 * 128)

 Obviously, if you only have a mono display these values will bear no
 relationship with the actual colours.

 NOTE:

 In the UNIX and other environments the colour values also change radically
 to reflect the machine capabilities.
