To make rooms flow with color, repeat your tight two- to three-color palette throughout spaces. Use variations of the same hues, like greens in pillows and wall paint, across adjacent rooms. This repetition ties rooms visually, creating harmony and seamless transitions. For instance, if your living room has green tones, incorporate those greens subtly in the breakfast nook cushions or bedroom accessories. Consistency ensures your home feels planned, personal, and more spacious.
