José Francisco Xavier de Salazar y Mendoza is low-key throughout, a quality associated with Nocturnal Bister - deep shadows dominate the composition. Warmth dominates - the palette of José Francisco Xavier de Salazar y Mendoza leans heavily on the yellow-orange-red arc of the colour wheel. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 1.9% is devoted to #9A6C5B, yet that small allocation delivers the palette's entire chromatic tension. The value range of 50 units sits in the comfortable middle: enough depth, enough light, neither extreme. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. This is palette 3 of José Francisco Xavier de Salazar y Mendoza's sequence - a single chapter in a chromatic story told across many works.
