The value structure of Johannes Joseph Destrée is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 9.8% is devoted to #998A59, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 72 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Johannes Joseph Destrée arrived at this balance through long practice; the palette carries the weight of that experience.
