Values in Jeong Seon rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is measured and controlled, giving the palette presence without visual aggression. #AE985E at 26.8% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The chromatic peak belongs to #B9A570, and at 15.7% it dominates, not decorates. Spanning 54 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 4 sits within the larger chromatic argument that Jeong Seon's complete body of work advances.
