Do you mean something like:

camera {location <0,2,-4> look_at 0}
light_source {<-1,50,10>, rgb 0.4}

torus { 1, 0.1
  pigment {
    radial
    color_map {
      [0.0  color rgb <1,0,0>]
      [0.3  color rgb <1,0,0>]
      [0.3  color rgb <0,1,0>]
      [0.6  color rgb <0,1,0>]
      [0.6  color rgb <0,0,1>]
      [1.0  color rgb <0,0,1>]
    }
  }
}
