if the color range you are after is contained in one of the existing
color scales, you can just set the color scale data range so that
only those colors are generated. so to turn RWB into a RW scale
you would just need to double the upper value of the data range.

second you can redefine the colors of one of the given scales.
color scale BlkW {0.1 0.0 0.0} {0.4 0.0 0.0} {0.8 0.0 0.0}
should do something along the lines of what you want.

cheers,
