Jean-Baptiste van Loo is low-key throughout, a quality associated with Abyssal Sienna - deep shadows dominate the composition. Warmth dominates - the palette of Jean-Baptiste van Loo leans heavily on the yellow-orange-red arc of the colour wheel. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 1.2% is devoted to #C0A75C, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 57 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Jean-Baptiste van Loo's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
