For interior doors, molding, and trim, I use Sherwin Williams Super White in Semi-gloss finish. For ceilings, I use Sherwin Williams Ceiling Bright White (it's a Flat finish). Don't forget to paint INSIDE the closets.
If you have a tray ceiling in your home, it should be a dramatic focal point of the room. One of the most common ways to emphasize your tray ceiling is to paint it a color other than builder beige or white like your ceiling. Luckily, there.
