and here I can answer you:

#local f_pig=function{pigment{agate}}
#local f_red=function{f_pig(x,y,z).red}
#local f_green=function{f_pig(x,y,z).green}
#local f_blue=function{f_pig(x,y,z).blue}
#local Pig=pigment{
average
pigment_map{
[1 function{f_red(x,y,z)} color_map{[0 red 0][1 red 3]}]
[1 function{f_green(x,y,z)} color_map{[0 green 0][1 green 3]}]
[1 function{f_blue(x,y,z)} color_map{[0 blue 0][1 blue 3]}]
}
}
