Obangsaek, the Korean traditional five-color palette: a flat-lay still life on a white hanji paper surface using ONLY the five colors blue, red, yellow, white and black — a folded saekdong striped silk sleeve, a small red and blue lacquered wooden box, a yellow silk pouch with a knotted cord, a black ink stone, and white porcelain. Every object is one of the five colors, nothing else. This is Korean, NOT Chinese or Japanese decoration — no dragons, no cherry blossoms, no gold. Even overhead daylight. No text, no letters, no characters anywhere.
