Well, yes, it does look wierd at first. The point is that it is far more 
flexible...a pigment is just a function that returns an RGB color 
vector, a color map is just a vector spline, which is also a function. 
If you want interpolation in a different color space, just convert back 
to RGB for the final value. If you want your own custom function instead 
of a color map, no problem. It can express any existing POV texture, and 
much more, without being much longer if at all.
Adding a special color map feature just adds bulk to an already 
redundant feature.
