The value structure of Johann Anton de Peters is mid-key: quiet, controlled, and cohesive. Johann Anton de Peters builds on cool foundations: the palette favours the blue-cyan-green arc. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 5.8%, #6B4C2E carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Spanning 48 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 3 of Johann Anton de Peters's sequence - a single chapter in a chromatic story told across many works.
