Keep in mind that your painter can add more than one color or shade to a room. Professionals suggest painting an accent wall with a distinct color or painting molding with a contrasting shade or finish to highlight it.
If you have a showy garden that you’d like to highlight, choose a paint color that will do it justice. For instance, architect Kelly Haegglund chose a bright green door (see first image), because “it’s modern, and a complement to the greens and purples in the garden.” And I’ve noticed that darker house colors often make the colors in a garden pop. 7. But white will never be a bad choice. Above: For this house in Connecticut, Brooklyn’s O’Neill Rose Architects used low-luster Benjamin Moore Brilliant White, which principal Devin O’Neill calls “a standard that always looks good.” The firm worked with Donald Kaufman on the palette for the house and chose Donald Kaufman Color DKC-44 in semi-gloss for the porch and ceiling.

Examine your home for areas where paint has lifted, is peeling, or curling up, as you’ll need a smooth surface before you begin the paint application. Gently scrape loose paint with a wide paint scraper and a wire brush.
After you've rolled-out each strip you'll want to tip-off each one as you go, by very gently rolling over it one final time - going from ceiling to floor with each pass to give it a smooth final appearance.
