What color should I paint my outdoor light post. Where can I get paint?

All light posts should be painted Sherwin Williams Tricorn Black SW6258 in a matte finish. 
​Get it at the Sherwin Williams store near Powers and Dublin (6345 Source Center Point, Colorado Springs, CO 80923, (719) 260-1767) or take the information to any Home Depot or Lowes hardware stores and they can mix a match.
