I know that it comes in different types, but I never really did anything that... precise, so I'm not one to talk..
However, do keep in mind milliput (at least) comes also in black and terracotta - for me that was a MAJOR plus, cause I didn't have to paint those (let's say painting is not a strong point)..
I used those for the trolls - terracotta for the mother's top and the black one for the kid...
