AVERAGED:

cylinder { 0*y, 1.1*y .4
   pigment {
       average
         pigment_map {
            [1,     onion scale .1
                   pigment_map { [0 rgb 0]
				[.5 rgb 1]
				[1 rgb 0]
		  }
            ]
            [1,     radial frequency 9
                   pigment_map { [0 rgb 0]
				[.5 rgb 1]
				[1 rgb 0]
		  }
            ]
         }

   }
}


NESTED:

cylinder { 0*y, 1.1*y .4
    pigment {
       onion scale .1
       pigment_map {
           [0 rgb 0]
           [.5      radial frequency 9
                    pigment_map { [0 rgb 0]
				[.5 rgb 1]
				[1 rgb 0]
		   }
           ]
           [1 rgb 0]
       }

    }
}


COMBINED AS FUNCTIONS (one variant of many):

#declare pO =
function {  pigment { onion scale .1
                       pigment_map { [0 rgb 0]
                                     [.5 rgb 1]
                                     [1 rgb 0]
		      }
             }
}

#declare pR =
function { pigment { radial frequency 9
                      pigment_map { [0 rgb 0]
			           [.5 rgb 1]
                                    [1 rgb 0]
		     }
            }
}


cylinder { 0*y, 1.1*y .4
    pigment {
        function { pR(x,y,z).grey + pO(x,y,z).grey }

    }
}
