Well, PSP is telling me that there are 249 unique colors in the grayscale map, but only 6 (as you indicate above) in the gradient/color file. I don't know enough about how PSP works to figure out how to apply those 6 colors to the 249-shades of gray and make the map colored. Guess I'll just grab another PTO map somewhere, if I can find one. Thanks for trying to help
