You can set !p.background to the index in the CT you want. Not sure
about foreground. However, I leave those alone and customize the CT
itself like this:

TVLCT, r,g,b, /GET
r[0] = ( g[0] = ( b[0] = 255 ) )
r[255] = ( g[255] = ( b[255] = 0 ) )
TVLCT, r,g,b

I cannot replicate this. For me the default CT is grayscale with
index 0 as black and 255 as white so color=250 is almost-white.
Perhaps you are running a site-wide startup file that is
initializing a CT for you with red at index 250?

If you want yellow/blue/green color you need to
a) make sure they are in your colortable
b) figure out where they are
c) then use the color=(a number) syntax to access them.

-k.
