Beiges are a great color to keep rooms as open and warm as possible. They also make a wonderful neutral palette for art and wall decor.
Blues help to evoke serene, calming emotions. Great for walls but also great to accent a certain part of the home, like kitchen cabinets.
Grays are the most in-style color that still provides a neutral palette in a variety of tones, making a room either cooler or warmer.
Accent colors are used as a highlight and can add a nice pop to any room in a home, like the dining room, a bedroom, or the bathroom.
