One way is to use the PRINTER graphics device, with a color PostScript
printer (such as HP Color Laserjet PS) selected for output to a file,
e.g.

entry_device = !d.name
set_plot, 'PRINTER'
result = dialog_printersetup() ; Select HP Color Laserjet PS to file
device, /true_color
plot, indgen(10), color='FF0000'XL
device, /close_document
set_plot, entry_device

This creates a bright blue plot in IDL 5.3 for NT4. The printer dialog
takes a bit more patience on UNIX platforms, but it does work.

Cheers,
Liam.
