Hong Kyoungtack has explored the theme of obsessive desires in modern life through everyday materials such as pens, pencils, and books. Additionally, he has opened up new possibilities in painting by traversing between design and painting, blending pop art and realism, while also achieving a universality that resonates with people. Since the 1990s, Hong has experimented with his own unique style, influenced by pop art, geometric abstraction, and color-field painting, incorporating bold primary colors, contrasts in color, and rhythmic compositions. 

In Hong’s ‘Pen’ series, the everyday object of a pen is densely interwoven in a spectrum of vivid colors, depicted in a state of explosive energy—as if a fountain were surging upward or flowers were in full bloom. These ordinary items, rendered in large-scale, intricate compositions on canvas, become unfamiliar to the viewer, evoking a sense of abstraction. Hong describes the tightly packed structure, with no empty space, as 'an extreme expression of the compulsions derived from reality.’
