Louis-Amable Crapelet works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #8C6B49 - appears at just 6.0%, deployed as a precision accent against the quieter ground. At 71 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 3 of Louis-Amable Crapelet's sequence - a single chapter in a chromatic story told across many works.
