“Sans titre” is based on a copper-colored yellow brown tone that was only characteristic in the 1960s. The painter's thoughts are rushing in the large space with abundant quivering color gradation and slight sensitive jumping lines. Both lightness and heaviness show in the painting. The emotion is like circuitous windings at this moment but instantaneously the seas are rising and surging to strike the hearts of people watching. Though facing fear in his heart and depression in his soul, Zao Wou-ki still uses his harmoniousness-loving free will to give an upward spirit to his painting. He has mastered the secret of color and light-shadow space. His style looks splendid with abundant painting elements. Zao Wou-ki was born in China with its long history. Compared with European abstract painters at the same time, Zao’s cultural heritage, and ancient historic tracing in his paintings give him more abundant background elements. Over hundreds of years, Chinese painting masters used literary devices and ink plays, high mountains, and fishing in seclusion to express themselves in their paintings. They were not painting real landscapes but expressing their innermost microcosms. Zao Wou-ki also cherishes a grand ideal to open a space for himself to meditate freely in the studio on the foreign land.
