This command:

out = TVRD()

Now you have the variable out as an 8-bit image. So,
you have to Set_Plot to WIN, re-load your colors,
and set color decomposition OFF to see colors:

Set_Plot, 'WIN"
Loadct, colors, 1
Device, Decomposed=0, Get_Decomposed=curState
TV, out
Device, Decomposed=curState

Of course, you *could* use TVREAD and TVIMAGE and you
wouldn't have to worry about most of this. :-)

Cheers,

David
