Base sensory perception is way more subjective than objective. Two people will simply taste differently, and there's only so much you can do to bring legibility and objectivity to the table. The surface area of the physicality with the brain is too large. Color on the other hand is measurable and regular across humans to a far greater extent, such that we can measure with a fairly high degree of accuracy just how color-blind a person is. That's what's seductive about it. You don't have that with other aspects of sensory perception.
