On a simple colour wheel blue is the complementary of orange. On a wheel with double the complementaries blue-green is the complementary of red-orange. These are both pairings for which I have a liking. So it wasn't a surprise that I should stop by an old blue-green door in a garden wall made of orange brick with Boston Ivy that was starting to acquire its autumn colours and take this photograph.
