Another solution would be to add a slight translation to your color_map, which
will pull its sharp index-list "crossover" position away from the cylinder's
end cap:

         pigment {
                 gradient x
                 pigment_map{
                         [0.0 color Green filter 1]
                         [0.05 color Green filter 1]
                         [0.8 color Green filter 0]
                         [1.0 color Green filter 0]
                            }
                  translate .0001*x

                  ...etc. ....
