Jean Monchablon works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #403A23 - appears at just 7.9%, deployed as a precision accent against the quieter ground. The value range spans 62 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 1 of Jean Monchablon's sequence - a single chapter in a chromatic story told across many works.
