Subject: Using colour to indicate response intensity



Hello,

I'm looking for an algorithm to convert a number in the range, min >= n >= max, into a
colour. I've Googled for it but I can only find HSV to RGB conversions. The full HSV scale
is not suitable because it's circular. Plenty of people must have to do this, e.g.,
weather maps that use colour to indicate rainfall intensity. Is there a "standard"
algorithm that takes a single number in a suitable range and outputs the corresponding RGB
value for a linear rather than circular colour progression?

David
