This abstract ink painting features expansive washes of ink and colours, and a distinction between the upper and lower areas, which alludes to the sky and earth or ocean. The lower section contains a black field with ink splatters and lighter parts at the bottom. Liberal washes of red, black, and a small patch of green cover the upper area, suggesting light and cloudiness intermingling. Lui Shou-kwan trained in Chinese painting by copying works by masters. When he moved to Hong Kong in 1948, he studied Western art and began to incorporate abstraction into his work, which developed into his Zen Paintings series in 1962. This painting is part of his later Zen Paintings, which often reference the depths of the ocean. It shows the influence of watercolour landscapes, in contrast with the dry, brushy composition typical of other works in the series. Lui’s works reflect his examination of Zen and Buddhist philosophy, addressing ideas of boundlessness and an interconnected world. His innovative method, combining classical Chinese painting with Western aesthetics, led to the start of the New Ink Painting Movement in Hong Kong.
