You're not bad at all, John! It's just that whenever artists start talking about color and color theory, things get confusing pretty quickly. I think that a lot of artists say they object to too much color when what they are really trying to say is that they object to excessively high chroma in a painting.
By the way, Gamblin's 'color space' discusses historic and 'modern' pigments and is styled (somewhat) after the Munsell system. A good introduction to Munsell is
on Wikipedia here. I don't know much about the Munsell system beyond what's there.
