Yellow abstract shapes, perhaps suggestive of flowers, occupy the upper sections of Brian Clarke’s ‘Falling Water’ (G2-18, 2018). Imitating fresh paint dripping down a wall, yellow streams of varying thicknesses flow from the flowers to cover almost the entire surface of the stained glass folding screen. White, often synonymous with transparency, reveals here its opaque quality which alters the luminous potential of glass, modifying the way light is projected onto the screen’s surroundings.
