Since your room is large your color options with this room are quite broad

For your main color, we chose to use brown as it reminds us of nature and has a relaxing quality which is easy on the eye. Darker browns work well as accent colors and lighter hues like tan and beige can match and unify most rooms.

Use an eggshell finish paint which has a very light touch of shine (similar texture to an eggshell as implied by its name). This finish is very often used for walls and is more durable and easier to clean than matte finish
