Hmmm... You're probably right. I'd read Jim's problem as a need for a
general translation algorithm from a one dimensional value to three
dimensional RIB. An increase in the one dimensional value resulting in a
change in color towards a psychologically more intense color. An example use
of this could be a heat map.
Even if a lookup table or some type of search algorithm was required for the
reverse translation it could be useful.
