Johannes Christiaan Karel Klinkenberg distributes its values across the middle register, creating harmony without high contrast. 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. The most saturated colour, #695537, is reserved to 9.2% of the surface, where it acts as a focal punctuation. The palette spans 54 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. In the context of Johannes Christiaan Karel Klinkenberg's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
