I don't think it would be necessary to find areas in the painting with a pure primary (an unmixed pigmented paint).
What I think would suffice would be a sufficient number of areas of *flat* color, whether mixed or unmixed. Then the question would be *how many* of these sampled areas of flat color constitute a representative sample of the whole range of colors in the artwork.
Also, paint has a geometric component, due to its thickness and the angle at which it's viewed -- a raised glob of paint has many surfaces, and the angle at which each facet of that raised glob is viewed influenced the perceived color. I would think that that is an even tougher thing to measure and reproduce properly.
