Hi there... I have a program which works with a colormap that
is an array of 256 RGB triples. I would like to know if someone
has an algorithm (or even just the data) for generating a set
of 256 RGB triples that represent a rainbow? (The first entry
in the table would be (1,0,0) for pure red, and the last entry
would be violet).
I have a fairly decent version that a friend of mine hacked just sort
of from intuition, which doesn't look too bad, but it could be
improved.
Actually, I'd also be interested in hearing the reasoning
behind such an algorithm, if anyone can supply it.
Please reply via E-mail; if I get many requests from others,
I will post a summary. Thanks!
