John Singer Sargent works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 5.2%, #6E4025 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. John Singer Sargent's palette 10 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
