Low-key values are the structural spine of José María Casado del Alisal, giving it gravity and atmosphere. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 5.0%, #36160F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 67 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. José María Casado del Alisal's palette 5 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
