If he used MegaPatch, he could have typed
sphere {0,1 no_shadow pigment {red 1}}
sphere {0,1 no_image pigment {red 1 filter 1}}
instead...

Anyway, I described this method some months ago in p.g (subject:
'colored shadows' or something like that).

If you say so...

sphere {0,1 pigment {rgb <1,0,0>}}
sphere {y,1 pigment {rgb <1,1,0>}}
sphere {y*2,1 pigment {rgb <0,1,0>}}
sphere {y*3,1 pigment {rgb <0,1,1>}}
sphere {y*4,1 pigment {rgb <0,0,1>}}
sphere {y*5,1 pigment {rgb <1,0,1>}}
sphere {y*6,1 pigment {rgb <1,0,0>}}

Or isn't that what you asked for?
