one ! Thanks for sharing !

marble if you layer the color. Since your base colors are neutrals, gray and black, you can get away with just about anything . Blue, darker gray, or even maybe some green for a pop of color. I suggest painting a few large pieces of cardboard a color that you like and laying them down on the patio and living with them for a little while. You might be surprised at what grows on you or looks good. Good luck and happy painting !
