Here's an example:
#declare pig1 = pigment {bozo color_map {[0 rgb 0][1 red 3]}
translate 0 scale .2}
#declare pig2 = pigment {bozo color_map {[0 rgb 0][1 blue 3]}
translate 50 scale .2}
#declare pig3 = pigment {bozo color_map {[0 rgb 0][1 green 3]}
translate 100 scale .2}
#declare pig4 = pigment {average pigment_map {[1 pig1][1 pig2][1 pig3]}}
sphere {0,2 texture {pigment {pig4} finish {ambient 1}}}
camera {location -5*z look_at 0}
