Speaking of artistic vs. natural, I just ran across something in Vue that I didn't know existed:

"If the Variable color option is selected, the color of the light will vary with the distance to the light source (of course, the intensity of the light varies independently from the color). Although there is absolutely no physical justification behind this behavior, it can be used to create interesting effects on occasions (especially when using volumetric lights)."

Not sure how I might use it, but interesting possibilities.
