These got off to a slow start as I wasn't quite sure what to do. The in-game range covered most of the "natural" hair tones and then some. They didn't cover brown though:
I quickly fell in love with this mahogany coloured one. It wasn't one I'd intended to make:
Sooty brown with a red mane seems to work well too:
A swamp ape. This guy gets his greenish colouring from the algae growing in his constantly damp fur, much like a sloth:
A different kind of red to the in-game one:
Stark white with a brown face seems to look pretty nice. I think the contrast works better than the in-game pink-faced white/grey:
Gold. I tried to make a natural-looking blond but wasn't all that happy with any of them. This gold is the one I felt happiest with. It's more of a tamarin gold:
And since I was a child of the 70s, I couldn't help being a bit silly. Grape Ape, Grape Ape...
