Help naming/describing a colour

So lately I've been thinking about skin. The texture, the flavour...

Kidding, of course. :P But I have been thinking about skin *colour* among the humans in my world. I decided on a whim that the range thereof would somewhat exceed that of reality; I've no fantasy races on Median so a group of people with grey-blue skin is about the closest you get!

I've been intentionally avoiding real life terms for skin colour to distance myself from racial politics and avoid confusion. For example, some of my humans are black. But when I say black, I mean BLACK. Not black like 'black people' (who are really just brown) but proper FFFFFF black, or near enough. So I've instead termed this skin tone *obsidian*. Easy, done.

The problem I have now is a colour I can only describe as olive. Again, I'm not talking about the olive skin associated with Mediterraneans but something distinctly yellow-green. You know, like an olive (albeit more desaturated), or perhaps even a goblin. If you want a hex code, think CAD8CF.

I've been wracking my brain but I keep coming up olive. Any better ideas? Aside from obsiadian the other tones are shades of what I call sienna, auburn, rose, ochre, umber, amber and grey, if that helps (and I'm open to thoughts on these too).
