Mid-key values give Diogène Maillart its characteristic quietness - nothing blazes, nothing disappears. Diogène Maillart orchestrates warmth above all else - reds, ambers, and siennas take the lead. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The highest-chroma note - #DA622F - appears at just 3.5%, deployed as a precision accent against the quieter ground. At 78 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Palette 4 sits within the larger chromatic argument that Diogène Maillart's complete body of work advances.
