"he was telling you how to match colors and hold a brush" You have no cause to complain here in this analogy. Either quit or happily let him tell you how to match colors and hold a brush, and if he tells you to paint like the sloppy kids across the street, that's now your job. You're not painting for the City while having a superior, or for "shareholders" or to "build a good house" or "build a good company" (that this is a metaphor for) - you're painting for him. If you don't want to do it like he says, you would leave (or quote more money for putting up with his childishness.)
