There are so many great gray paint colors available today to choose from. One of my favorite grays is Wickham Gray HC-171. This gray that has a green undertone. It is a very successful color when used in any room in your house. It is part of Benjamin Moore's Historic Color collection. This timeless color looks just as good in a traditional spaces as is does in contemporary ones.
I like this color because it is a mid tone. It isn't too dark and it isn't too light. Some gray colors can look too saturated on the wall or look to light. Either situation is not great if you want to see your color on the wall but not overpower it.
