The palette of John Simpson sits in the lower register of the value scale - dense, contained, and weighted. Temperature reads distinctly warm: the reds and earth tones from John Simpson carry the compositional weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 35.6%, #050403 functions less as a colour accent and more as a complete atmospheric environment. Only 5.2% is devoted to #27120C, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 68 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 John Simpson's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
