Values in José María Casado del Alisal rest in the mid-range - neither dramatically lit nor steeped in shadow. José María Casado del Alisal builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. A single dominant - #23211A at 33.9% - sets the character of the whole composition. The highest-chroma note - #FEFDFA - appears at just 8.2%, deployed as a precision accent against the quieter ground. 74 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of José María Casado del Alisal's sequence - a single chapter in a chromatic story told across many works.
