I have created the attached scene.

It works well, except the pigment function needs to be offset at the 
beginning and end of the gradients "CSolid_HSLSphere_Saturation" and 
"CSolid_HSLSphere_Lightness". The end result is supposed to look like this:

Can someone clue me in on how to do this? Thanks.

Ignore this thread, I will start a new one without the dependencies.

This just looks like a 12-section radial pattern.
Make a color_map or pigment_map and start 1/2-way out of section 12, move along
normally, and you'll wind up ending 1/2-way through section 12.

Okay, but there are also 7 saturation steps, 7 lightness steps. So 12 x 
7 x 7 sphere chunks total! That will take too much effort for the time 
being.
