Values in Jules-Alexandre Grun rest in the mid-range - neither dramatically lit nor steeped in shadow. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 6.6%, #85704D carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 52 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Jules-Alexandre Grun's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
