TVLCT, [255, 0, 0], [0, 255, 0], [0, 0, 255], 1
Plot, x, a, Color=1
Plot, x, b, Color=2
Plot, x, c, Color=3

Cheers,

David

P.S. If you look on my web page you will find the program
GetColor, so that you could do this (I'm assuming 8-bit
display in this example, although GetColor also works
in 16-bit and 24-bit mode):

TVLCT, GetColor('red'), 10
Plot, redvec, Color=10
