My concern would be the doors and door frames of the painted rooms. Will those doors be next to or near stained doors?

The rooms themselves would have the stained door unless I paint that side of door. If I did paint the door on the inside, I guess I would paint the closet doors and bathroom doors. All the bedrooms have their own ensuite. My biggest problem I guess is that my windows are so high that I have no room for window trim and crown on the ceiling so I have to build the top of the window up so the crown will go along the top of the window. I would rather keep my crown painted so, if I go with stained trim how can I tie in the crown along the top of the window if the crown is painted? Not sure if that makes sense to you or not. My other option would be to keep the doors stained and paint all the trim throughout the house but I'm not sure if that would look right or not. Or, I could stain my crown as well.

Breaking stain and paint at a door is a fairly simple process. The door stop, the small piece of stock that the door shuts against is the break point. The outside corner of the stop, where it hits the door is the point that the paint goes to stain. Stained doors can work quite well with painted trim and painting one side of a door is common....think of the front door of the house, usually it is one color on the outside and a different color on the inside. The leading edge of the door matches the color it moves into, the hinge side is painted the same as the exterior. On the other hand, mixing painted and stained trim in a single room or together in a package is difficult. The crown moulding should match the trim it hits...whether that is painted or stained...actually, all trim should ideally be the same color or finish...ensuite. Stained doors work with painted trim....think about the contrast of a black or chocolate painted door in combination with a white casing and jamb...a striking contrast. Key is...no cheap wood! The door needs to be intended to be clear finished...stained pine at a minimum! Vertical Grain Douglas fir, knotty Alder, Cherry, Oak...these all work in fairly specific designs....Mahogany!

If the trim within one room would vary from stained to painted I would be inclined to go one way or the other. I am not postive I am following what you mean completely, however. In my bedroom I have painted trim including the crown, baseboard. We have two stained doors still and I am looking at changing them out. The door frames are stained and visible from both sides which also is an issue. If all the trim and doors are the same color in the same room, it looks better in my feeling.
