Since your room is large your color options with this room are quite broad and dark tones will provide rich depth and volume.

For your main color, we chose to use black because it is authoritative, sophisticated, and powerful. It is a good neutral counterpart to any other color. Black is used to give depth to a room as well as make a dramatic statement.

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
