Good wood fence paint colors include dark blue and purple. These bold colors make green foliage in front of the fence stand out, according to WoodFinishesDirect.com.
Raspberry red and magenta pink are other good colors to paint a fence to highlight green foliage, as they are contrasting colors. To create a contrasting effect without using overly bright pinks or reds, try dark brown or black. Darker paint colors are also useful to make a garden seem larger, and they are less susceptible to showing up grime and dirt than pale colors. Using two contrasting paint colors can help create a shabby chic look.
Another idea is to paint a fence in a color that matches the exterior of the house or the patio furniture, says Houzz.com. White is a classic fence color, which creates a crisp look and an inviting feel. A bold color such as blue helps add to a featureless backyard. A blue-green fence works well with a house with neutral colors as it acts as an unexpected accent. Alternatively, use a neutral color such as deep gray to make the plants the central feature of the yard and help blur the boundary between the garden and the horizon.
