True, but that's something you learn to do after you've learned what shadow maps do and I don't think the original poster was familiar with those yet. My feeling is that it's a little easier to understand what the shadow map is doing if you can see it's nothing but levels of light and dark (re: a desaturated layer). Adding color is an extension to that. I actually learned to do exactly what you suggest by first learning shadow maps and then tinkering with the process. So I guess you can modify my answer to change "always" to "often, especially when you're first learning shadow maps". :-) -- Michael J.
