I'm starting to think hueshifting implies that the hues are not blended in correlation to the actuallity of the situation. Meaning that the shift in hues is related to the artists whim, and not the technicallity of the suggested light.
Why am I thinking this? Because if it were based upon the technicallity and actuallity of the suggested light(since all color is derived from light), then there would be no real need for such a term. It is only when you disassociate yourself from the mechanics of light that such a term could mean anything because you'd need a way to describe your choice of color when your choice of color does not follow the commonly accepted rules.

If you are following the commonly accepted rules of light, then hue-shifting just means you are blending colors..

I think the term is needed more to describe the slight change in hues from shadows to highlights that is present in reality as opposed to the strict variation of luminance often present in pixels. However, the term could apply to any changing of a hue--calling hue shifting the shifting of a hue isn't far from the truth.

Thanks for all your input.  It was very helpful to me.

What hue would white shift too?  Does it not? Can it go to all colors? Or does it go to gray only?

White would shift to anything. Honestly though, white should be restricted to use on highlights.

See the diagram here:

(It's probably not exactly shaped like this if you looked at actual values, but I don't have that data and this should be close enough.)
This shows that as luminosity nears extremes, the saturation you can show decreases, meaning that black and white can be any hue because at the ends of the luminosity continuum you get no saturation. That there's no saturation results in any hue producing the same color as any other. You can shift white and black to anything, but they really don't have any standard shift because they themselves aren't hues.
