The value structure of Martín Rico y Ortega is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #B18B5D - appears at just 7.5%, deployed as a precision accent against the quieter ground. At 61 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. The palette is a signature: Martín Rico y Ortega's particular sense of value, warmth, and colour weight made legible.
