Alex, I assume you mean powder pigment, because watercolor pigment
wouldn't mix with the rubber cement. That sounds like quite a good idea,
in fact -- assuming it will mix. The rubber cement hardens so quickly as
the solvent evaporates that you wouldn't have a lot of time to blend it
in. But pigment might be the "solution" for masking a complicated area.
(Simple ones you can just put on, no problem.) I'll try it. Thanks.
