My home is an open plan and am looking for a paint that can cover a stippled ceiling that was painted an off white. The rooms that would be off the open plan are Bathroom, bedrooms, laundry room. I would like suggestions on type of paint for good coverage for that type of ceiling and a color that will blend well with all other paint colors throughout the home. I tend to like earthy, beige, taupe, creams colors for walls. Also, trims is it best to choose room to room or the same color throughout especially an open floor plan and would like a color that blends well with other colors. I got a gift certificate at BM so would like to use up soon. More economical buying gallons than quarts of this and that. Thanks as I really need some suggestions.
