Jeong Seon occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #786134 - appears at just 2.5%, deployed as a precision accent against the quieter ground. The value range spans 55 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. The palette is recognisably Jeong Seon's own: particular in its temperature, chroma, and the economy of its brightest note.
