Domingo de Aguirre is strongly light-biased - shadow is suggested rather than declared. Domingo de Aguirre builds on cool foundations: the palette favours the blue-cyan-green arc. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 3.8%, #595329 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Value range is moderate at 50 units - enough contrast for legibility, not so much as to fragment the tonal unity. 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 Domingo de Aguirre's sequence - a single chapter in a chromatic story told across many works.
