Herman Johannes van der Weele distributes its values across the middle register, creating harmony without high contrast. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #161008, is reserved to 11.9% of the surface, where it acts as a focal punctuation. The full value range is 67 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Herman Johannes van der Weele's complete body of work advances.
