I am pleased to see the reference to Munsell. (I used Munsell in part
to help with the design of the original set of XO colors and use it in
the Color Deducto activity). But I think if we were to go this route,
we won't need to burden the end user with needing to know about
Munsell; we can add a hue/value/chroma family for each XO color from
which we could improvise as part of xocolor.py. It'd be a nice
addition independent of this particular feature proposal.
