The zoo called this a “talapoin”, but there are two species of talapoins, the Angolan and the Gabon. Not knowing what made them different, I went a-searchin and came across the following claim:

“Unlike the related Angolan talapoin, the Gabon talapoin has flesh-coloured (not blackish) ears and facial skin.” (from The Kingdon Guide to African Mammals, by way of Wikipedia)

Now maybe it’s just me, but it seems that the ears and facial skin or any monkey, whatever they look, would be flesh-coloured.

Crayola’s got a lot to answer for.
