Note the colors of the spheres.
Note the colors on the ground.

How was this done?

I suppose the spheres are using solid colors, and the "colored spots"
on the ground which might appear to be shadows to some, are actually
transparent discs. Is this close?

This is one way of doing it very easyly:

sphere { 0,1 no_shadow pigment { rgb <1,0,0> } }
sphere { 0,.999 pigment { rgbf <1,0,0,.9> } }

and so on.

Parallel light source in Mega POVray? Even the black one.

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).

 
> and so on.
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?

I figured it was some type of shadowless and filter stuff. It looks like it
has radiosity, either that or all seven spheres are textured together using a
radial angle hue and radial distance chroma.

"Scene contains 8 frame-level objects; 1 infinite"

Nope!

Rendered using the SuperPatch 3.1e.

This won't account for the shadows.
