Can the color of the light reflected off a bump-map be adjusted, or is it just taking the texture colors and gradating them according to the light-source color?

Someone else will answer more authoritively but to the best of my understanding the bump map just uses the color channels to hold the angle of the surfaces to the normal perpendicular (the 'normal map') so although looking at a normal map is multicolored I think it only changes degrees of brightness in-game to represent the contour of the surface. I guess you're talking about reflected light color?

Yeah.
And the contrast often seems too strong, making almost every bump-mapped texture look overly coarse, wet, oily, melted, plastic, crusty, etc., incorrectly. I'm hoping there are ways to tweak things to look less artificial for all the added detail, instead of just another kind of artificiality requiring higher processing. As we know, materials reflect and refract light differently than one another, and that might be a next step toward creating a natural look and getting very different materials to look like very different materials, of the correct level of weathering, wear, manufacture, and so on.

I think that level of control will be beyond us until the d3 source is released. The D3 light interaction settings are handled by one file, the interaction.vfp file. Some of the later idtech4 games broke the lighting chores into separate files to allow for better control. We can't do that yet unfortunately.

Thanks. I suspected it wasn't available, nor easy to make happen.

Too bad the blog article itself has got some major inaccuracies.
Dangit, Marcel! *shakes tiny fist*

That article is such a piece of crap it would have been better of not being written.
A "port of Thief 3"?
Get out.

Someone from the team ought to post a comment on his blog, or at least email him and have him straighten that mess out.

The poor beginning:
"Thief - Deadly Shadows was a brilliant game." and the golden "The Dark Mod is rather a port of Thief 3"
ROTFL
I stopped reading here.
