Hi, can anyone provide a pointer to an algorithm which will produce a
false-color representation of a range of integers? I'm thinking of a
false-color spectrum representing elevation, like the one used in the recent
color digital elevation map created of MARS by laser rangefinding.
Essentially, the problem is this: Given a normalized elevation range, say
from 1-256, is there a convenient algorithm available to produce RGB values
which will produce more-or-less visually equal spacing on a color "spectrum?"
I realize there is no simple straight path through the RGB color cube which
will produce a perfectly visually ordered transitional set of colors. But is
there one that is even close?
Thanks in advance for your help...
