thier is two colour contol systems CIE Lab and CIE luvshade and hue and hue are part of the luv system more used by artits
us industrial guys used CIE lab I was refering too colour strenght.
This is very good info. I am a visual arts dabbler, so my question makes sense from my frame of reference. I am sorry I don't know anything about the science of light, e.g. color. Though I did see a visual instalation piece at a museum where the artist used mirrors,and other interuptors, to disrupt a spectrum into the semblance of a lanscape. More science that art and quite a beauty!
