Another slightly different perspective:

Neutrals are colors that the individual can wear and not look bad, but they need the energy/interest provided by texture or additional colors to look interesting.

I had my colors *done* in the '80s when it was all the rage. In addition to my Reds, Eye Extensions, and Lights/Whites, my swatches are divided into Dramatics, Understateds, and Neutrals. My Neutrals include colors one would expect such as my grays, beiges/taupes, browns, and navys. The ones with the least energy for me, however, are forest greens and burgundys. A ponte or other plain dress in one of those colors doesn't make me look sick but it just doesn't do anything for me. My *Dramatics* tend to have more energy than I prefer, so when I'm not mixing grays, I mostly stick to my *Understateds* which include plum, yellows, yellow greens, orange, and a few blues.
