How to Decorate Your Home

Paint colors are notorious for appearing different hues in different light conditions (and seeming to change between the paint store to home). This effect is only amplified once you slather it on four walls. For that reason, it’s never a good idea to commit to a paint color when you first see the chip in a store. Look at the largest chip you can get in the room you plan to paint, at a minimum. Better yet, paint large sample patches on walls or on boards that can be moved around and view them at different times of day.

Note: As long as you test the color before painting the entire room, there’s no reason to be scared of bold, saturated colors .

Once you have a color selected, choose the sheen. Matte or flat paints offer a pleasant gauzy appearance that also hides wall imperfections, but can be difficult to maintain, clean and touch up. “I tend not to do matte walls, in general,” said Ms. Hampton, who prefers paint with an eggshell or satin finish that is just slightly glossier and easier to scrub.

Baseboards, moldings, doors and other trim can be painted the same color as the room to make them visually recede, or a contrasting color — usually an off-white in a room with colored walls — to make them more of a feature. Trim can also be painted with a different sheen than the walls. A semi-gloss sheen will bring more attention to moldings while adding durability.

You should also decide how you want to treat the ceiling. You can paint it white for a crisp feel, or the same color as the walls for a cocooning feel. It’s safe to use a matte or flat sheen because the ceiling is rarely touched by dirty fingers or smudge-creating objects. If the surface is perfectly smooth, it can also be painted with a glossy finish as a design feature that reflects light down into the living space. (If your ceilings aren’t smooth, don’t do it — the glossy sheen will only highlight imperfections.)
