Blue and yellow are complementary colours: the blue of the bricks and the bluish-grey large photo of the old gate of this small court, and the yellow leaves go very well together.
Blue and yellow, fragility and impermanence are also to be found in my drawing of a Swallowtail and a Broad-bodied Chaser.
