The value structure of Rik Wouters is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #662D24 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.1%). At 65 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Rik Wouters's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
