Tschoon Su Kim's work is rooted in a tradition of gestural abstraction and the use of the color blue.^[1] Since 1990 Kim has been painting almost exclusively in blue. He researches the color's different shades in work series called Ultramarine, Blanco y Azul or Weiss und Blau and herein wakens up associations of water, heaven or trees without really having painted them.^[2]

"And that, again, means that Tschoon Su Kim's images are not only about distributed form, but also about painting itself. So they constitute an innovation of tradition, which makes them important, and of great import on contemporary art."^[1]
