Jusepe de Ribera is low-key throughout, a quality associated with Nocturnal Bister - deep shadows dominate the composition. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. A single dominant - #0B0808 at 25.0% - sets the character of the whole composition. At 6.3%, #492718 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 71 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Jusepe de Ribera's palette 10 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
