I guess you mean the `translucency` setting.

No, use neither the pigment colour nor black.

This is actually not a colour /per se/, but rather a value related to
the average distance a photon will travel inside the material before
being absorbed/scattered/both (can't remember the exact interpretation
off the top of my head), which can be specified differently for the
three colour channels (R,G,B).

There are no limits to the setting -- particularly translucent materials
might have values like <10,10,10> or even higher, while "dense"
materials might have values like <0.1,0.1,0.1> or even lower.

I'd start at <1,1,1> and see how it looks. If the material appears too
waxy, reduce the value. If it appears too "hard", increase the value.
