Francesco del Cossa distributes its values across the middle register, creating harmony without high contrast. Temperature reads distinctly warm: the reds and earth tones from Francesco del Cossa carry the compositional weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #914B39, registers at 5.7% - sparse enough to feel like a deliberate surprise. At 61 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 4 of Francesco del Cossa's sequence - a single chapter in a chromatic story told across many works.
