Charles Maurin distributes its values across the middle register, creating harmony without high contrast. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. All colours lean toward grey, building depth through value rather than colour punch. At 4.6%, #7C723C carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 68 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Charles Maurin's sequence - a single chapter in a chromatic story told across many works.
