Low-key values are the structural spine of Rafael Tegeo, giving it gravity and atmosphere. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Rafael Tegeo gives 32.9% of the composition to a single #151210 - a decisive chromatic anchor. At 2.9%, #CD8D60 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 80 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Together these qualities place Rafael Tegeo firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. This is palette 1 of Rafael Tegeo's sequence - a single chapter in a chromatic story told across many works.
