Values in Antoine-Francois Callet rest in the mid-range - neither dramatically lit nor steeped in shadow. 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. #4C2319 delivers the chromatic peak at only 8.4% - a small shot of colour with outsized visual impact. The full value range is 69 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Antoine-Francois Callet's sequence - a single chapter in a chromatic story told across many works.
