Is it possible to have 2 colors (red, green) and give a percentage of attenuation.
Example:
black (# 000000) => white (#ffffff) --- Percentage: 50% => gray (# 808080)
Is this possible with jQuery xcolor , if so, how?
(the xcolor.analogous example returns around the colors that I want to have, but how can I set the decay percentage?)
It seems you almost answered your question: the xcolor plugin you are pointing to has exactly the method you want:
$.xcolor.gradientlevel(color, color, position, size)
Your example:
$.xcolor.gradientlevel("#000000", "#ffffff", 50, 100)
