That beats my method, which was to make a preliminary plot with no data,
just to set the colors!
plot, X, Y, /nodata, color=0, background=255
oplot, X, Y, color=4

One way to do this is to modify !P.COLOR and !P.BACKGROUND
!p.color = 0
!p.background = !d.table_size-1
plot, ...
Or, you can reverse the color table
tvlct, r, g, b, /get
tvlct, reverse(r), reverse(g), reverse(b)
