The palette of Rachel Ruysch sits in the lower register of the value scale - dense, contained, and weighted. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #06060C claims 37.9% of the surface, functioning as the work's tonal foundation. Only 3.2% is devoted to #D6A968, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 63 units of the value scale - a span that creates natural depth. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Rachel Ruysch's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
