Darkness anchors Henry Raeburn; light is rationed, creating dramatic contrast rather than open air. Yellow, ochre, sienna: warm hues that Henry Raeburn deploys as the palette's primary energy. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Henry Raeburn gives 29.5% of the composition to a single #271818 - a decisive chromatic anchor. The saturated accent, #905F32, registers at 5.3% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 76 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. In the context of Henry Raeburn's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
