Todd,

when you mix 3 saturated colors trying to make neutral you create the exact 
conditions for metamerism, no matter what the other qualities of the colorants 
may be. That's because your neutral will have a discontinuous spectral 
distribution (3 peaks) which may reflect light very differently depending on the 
spectral makeup of the light source. 

Until some technology overcomes this basic principle, quad or hex grayscales 
will be superior to the best of ICC-managed gray mixes of CMY.
