Pictures?

Since I prefer all mouldings to be the same, whether stained or painted, if I planned on keeping the stained, I would replace the crown with wood and stain it to match, rather than put the white up. If you plan on painting the rest of the trim, then just reuse it. Pictures of your room would definitely help.

That's my hallway. Rest of the house is the same.

Any thoughts?

I would remove the crown molding altogether. IMO, it doesn't work with slab doors.

If you want crown molding & painted trim, then you need to change the doors to a traditional recessed or raised panel design. Depending on the windows & other things (like style of fireplaces, etc.) changing the trim style may be a 'don't'....like if the house is decidedly mid-century modern.

I like the fresh look of white painted ceilings, moldings, base boards and doors, and I think they look great with a colored wall.
