Mid-key values give Louis de Schryver its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. At 1.3%, #9B5639 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The palette spans 44 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Louis de Schryver's complete body of work advances.
