CPAN Module for Normalizing to Green-Yellow-Red Color Scheme?by shoness (Friar)
|on May 06, 2010 at 23:32 UTC||Need Help??|
shoness has asked for the wisdom of the Perl Monks concerning the following question:
Suppose I have a linear integer scale with GREEN assigned to the uppermost scale value and RED to the lowest scale value. YELLOW is assigned to the median scale value. (Like a traffic light that uses HTML color codes.)
If my scale is from 0 to 2, my color choices are easy.
When I have a larger scale, then it's more difficult. For instance, if my scale is from 0 to 10.
There must be a CPAN module to help choose these (web-safe) colors, but I can't find one via searching...
Thanks for your help!
