Thank you! This was the correct solution.

For instance:

#declare CSolid_Div = 6;
#declare CSolid_HSLSphere_Lightness_stepped = function { 
floor(CSolid_Div * (f_ph(x,y,z)+pi/2/CSolid_Div)/pi)/CSolid_Div};
#declare CSolid_HSLSphere_Lightness = pigment
{
	function {CSolid_HSLSphere_Lightness_stepped(x,y,z)}
	pigment_map
	{
		[0/2 color srgb 1]
		[1/2 CSolid_HSLSphere_Saturation]
		[2/2 color srgb 0]
	}
}
#declare CSolid_HSLSphere_Pigment = pigment {CSolid_HSLSphere_Lightness}
