The wonderful thing about grays is that they go well together. From gray greens, to blues to lavenders to beiges, all the grayed down tones of these colors are so easy on the eye and so neutral you really can use se different shades and still create flow in your home. Because you already have beige on some of the walls in your home, a gray beige (or greige) may be a good choice.

BALBOA MIST 1549 - "The color is so, so pretty! It’s just a whisper of a soft warm gray. On some walls, a very slight, slight, slight lavender undertone, but then on others, very slight, slight, slight green undertones. It’s just warm, light and lovely. You can’t go wrong with Balboa Mist." - Laurel Bern
