We are in our first house and learning all about painting "rules". So....the doors and frames in the hallway are painted a soft cream colour. Inside my son's room, he wants the walls a bright blue and the frames/door all done in a silver/grey. I am just not sure what part of the door frame I should be painting this colour? The door opens into his room. Do I do the sides of the door in the silver-grey as well as the part in his room. Where do I end with the silver grey on the frame/jam? Thanks for ANY and ALL assistance.
