We refreshed this 1920s Colonial in the Fairmont Hill Historic District in Brookline, Mass., by bringing in unique mixes of color, from a glossy pink dining room ceiling to a verdigris powder room, fresh grass green update to the primary bathroom, and a green and turquoise kitchen. A tangerine couch pops against a bird-branch pattern wallpaper in the living room, granting the owner’s wish to bring the outside in.
