Re: OK, let me rephrase the question.

If I shot an image of a perfectly white (or perfect grey card) piece of paper illuminated by an ideal light source (linear frequency/amplitude content through the visible spectrum), what would the light temperature be to ensure that all channels reported light levels of equal value?

There isn’t a flat line light source out there, so there is no way to ensure equal RGB values with any given source. Just to give you some idea of the complexity of the spectral frequency distributions of various light sources, have a look at the following link:
