% Use a color picker to get red, green and blue values of a color.:
% Example: RAL 2005: red = 255, green = 35, blue = 1
% Create variables from the values.:
\setvariables[ColorName][r=255,g=35,b=1]
\usemodule[mathfun]
% Define the actual color based on variables:
\definecolor[ColorName][% r={\REDmathexpr[.3N]{\getvariable{ColorName}{r}/255}}, g={\mathexpr[.3N]{\GREENgetvariable{ColorName}{g}/255}}, b={\BLUEmathexpr[.3N]{\getvariable{ColorName}{b}/255}},]%
