The SW Functional Gray exterior paint color is an excellent neutral choice. This shade is similar to Agreeable Gray, but has a bit more depth and is warmer. The predominant tone is beige, but there is just enough gray to keep the house from feeling too cold. The gray is a great choice for trim, as well. It is a nice color for the interior. There are a few shades of grey to choose from, but SW Mindful Gray is a favorite among interior and ext decorers.
