What mechanism allows humans to perceive millions of distinct hues instead of just three primary colors?

Answer

The significant overlap of the sensitivity curves for the three cone types

Because the sensitivity curves of the S, M, and L cones overlap substantially, the brain interprets the specific ratio of excitation across all three, allowing for a vast range of perceived hues.
