Yes, don't use indices 0 and 255 for *anything*, and
always use a white background color for your WIN device.
Then everything will work *perfectly*. :-)

!P.Background = 254
!P.Color = 253
TVLCT, 255, 255, 255, 254 ; White.
TVLCT, 0, 0, 128, 253 ; Navy blue.
Device, Decomposed=0

Then, like this:

Plot, findgen(11)
thisDev = !D.Name
Set_Plot, 'ps'
Device, /Color, Bits=8
Plot, findgen(11)
Device, /Close
Set_Plot, thisDev

PS file looks like the display, and visa versa. :-)

And, possibly, if you *really* want to do this correctly,
use FSC_COLOR to specify your colors. In other words,

PLOT, findgen(11), Color=FSC_Color('Navy'), $
Background=FSC_Color('white')

always works, too. And you don't have to muck around with
!P.Color, etc.
