Values in Frederic Soulacroix rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #A48867 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.5%). Value range is moderate at 50 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 4 of Frederic Soulacroix's sequence - a single chapter in a chromatic story told across many works.
