Rule #1 when learning a difficult process: Eliminate as many variables and
complicated steps as possible. There was a brand --Bocour? that made large
tubes of cheap watercolors for students. Something like that should do the
trick for a beginner. Browns and blacks are usually made of the cheapest
materials, e.g., carbon black and earth pigments and are quite permanent.

A wellknown book on carbon printing covers this in great details... Still,
the use of powder is not recommended to a beginner.
