The high-key values of Martin Schongauer give it an effulgent, almost bleached quality. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #EBE9E4 at 30.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 3.9%, #73613F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 63 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Martin Schongauer's sequence - a single chapter in a chromatic story told across many works.
