I've noticed in some material files that color is assigned to a surface in terms of Kd Ka Ks and texture values where each value is a four character field with each character being between zero and one. Is this a variation of Hue Saturation and Brightness?

It is a normalized percent stated between 0 - 1 and its between 0 - 255. Don't know what the d, a, & s mean though.
Maybe helpful pages...

I believe they are Diffuse, Ambient, and Specular. If you are wanting to convert, just multiple the values by 255.
Excellent. Gives me much to digest. Many thanks!
