Mid-key values give Edmond-Georges Grandjean its characteristic quietness - nothing blazes, nothing disappears. Edmond-Georges Grandjean tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The dominant colour, #A28D60, takes 31.8% of the total area, establishing the overall mood before any other hue is introduced. The highest-chroma note - #783929 - appears at just 1.0%, deployed as a precision accent against the quieter ground. At 47 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 Edmond-Georges Grandjean's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
