If I'm not mistaken, there is a POV macro that will convert HSL colors
to RGB values that you can use in scenes.  However, I have been having
trouble finding it.  Does anyone know where it is or of any equations I
can use to implement my own macro?

I've done it. Here's a version of HSL to RGB and also a macro for HSB to
RGB. The descriptions explain the difference. These versions work
without trig or vector functions. To be complete, I've tacked on RGB to
HSL and RGB to HSB conversions.

You will also find a hex2rgb macro posted in the same thread.
