Mid-key values give Alexandre-Gabriel Decamps its characteristic quietness - nothing blazes, nothing disappears. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. All colours lean toward grey, building depth through value rather than colour punch. #603D20 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.3%). From deepest dark to palest light, the palette traverses 69 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Alexandre-Gabriel Decamps's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
