defines the color combination or effect to be used
for palette position O. This is the background, or
color displayed when the value of the DEB image
for a particular pixel is O. (See tables of combina-
tions in next section on PALETTE statement.)
When you enter a DEB mode, DEBbg defaults
to 0 (black).

is an integer expression that sets the active pal-
ette. Valid ranges are 0-3 for the standard palettes
and 4 for the LUT palette. If you omit palette from
the COLOR statement, the active palette does not
change.
The values you specify in DEB COLOR statements
fall into three categories:
• a color selection for the VDC from the same ranges
as you use in the standard text mode. These selec-
tions produce the same effect on the screen as they
do in the standard (non-DEB) text mode.
