This is one in a series of paintings in which Kidner aimed to create a dynamic colour relationship. The strict control of the colour on the surface of the canvas dictated the image. In interviews, he has explained how he alternated bands of orange and violet, starting at the top with a broad band of orange and a narrow band of violet and finishing at the bottom with a broad band of violet and a narrow band of orange. The curves occurring in every other band create a vertical alternation of orange and violet to oppose the more evident horizontal one. This work relates to earlier paintings, when Kidner had been impressed by the effect of sunlight on sand.
