I have backported this, with the addition of
rules: create new color table based on user-specified rules
as needed in 6.4.svn.


Related wish: could the list be printed in alphabetical order?
While the colors.desc file is ordered, the help text is no more:

r.colors help

   color   Type of color table
           options: aspect,aspectcolr,bcyr,bgyr,byg,byr,curvature,

            byg: blue through yellow to green
            byr: blue through yellow to red
            curvature: for terrain curvatures (from v.surf.rst and
r.slope.aspect curvature colors)
            differences: differences oriented colors
            elevation: maps percentage ranges of raster values to
elevation color ramp
            etopo2: rainbow color ramp for the ETOPO2 2-minute
Worldwide Bathymetry/Topography dataset
            evi: enhanced vegetative index colors
            grey: grey scale
            grey1.0: grey scale for raster values between 0.0-1.0

I am not sure where the order magic is.
