Hyong-Keun YUN (1928-2007) had positioned himself as one of the most important Korean contemporary artists, after introducing himself to the art world in the late 1960s. After graduating from Hong-Ik University in 1957 with a BA in Western Painting, YUN had held his first solo exhibition in 1966. For nearly 40 years until his passing in 2007, YUN had actively exhibited his artistic talent, basing his productions in undeviating manner in regards to his original concept of psychological and abstract expressionism. YUN’s paintings show the artist’s personal views on life and mother nature, while refusing to be confined within formality. In other words, his paintings are products that represent not only his own physique, but also the traces of his life, and the life itself. Once appraised as ‘a minimalist and an abstract artist who bears profound Oriental sentiments’ at the 46th Venice Biennial, YUN was consistent in regards to his artistic style of monochromatic paintings. After experiencing l’art informel of the Korean Abstract Expressionism in the late 1950s, YUN began producing abstract and expressive paintings composed of vertical elements in the early 1960s. From 1970s, YUN developed his style to produce wide and thickly brush stroked paintings that exhibit carefully placed, columnar elements which amply fill the pictorial space. Technically speaking, ‘form’ is nonexistent on YUN’s paintings. Instead, only colors such as dark brown and dark blue identify the different fields on his canvases. The margins and the colors on YUN’s canvases experimentally, however, successfully blend and fuse the finite and the infinite, the plenitude and the inadequacy and expand them to new degrees of possibilities within the field of abstract expressionism. YUN attempts to enlighten the audiences’ deep inner side while relieving them of visual pleasure. They are shelters to stop and cogitate about life, provided for those who live in restless reality.
