Awnings are a natural place to incorporate the charms of green, especially if you want something that will blend, rather than pop, against a mature garden. Adding in some inspiration from other natural elements, such as the sky, can bring subtle interest that won’t dominate but will wear well with the forgiving qualities of the pattern.
A spring green or a pale blue can give a French Riviera feel on a little balcony or a classic English Country house feel across a wide outdoor dining area. The tones also give the added benefit of cooling the feel of any strong midday sun. (Hope springs eternal for the British summer).
