Our units are wooden and are about 40 yrs old and are on an oceanfront bluff in So Cal. We are trying to choose new colors, and have about settled on using 4 randomly throughout the development. We do have quite a few trees as well. A couple of folks want to paint our units dark or medium brown, but most of us feel that would be depressing, and favor, still intense color, but ranging more toward grap, dark green, or tan/taupe/ Thoughts?
