Amadeo de Souza-Cardoso is strongly light-biased - shadow is suggested rather than declared. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. At 6.9%, #AF3C1E carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 68 units: broad enough to build convincing three-dimensional form. 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 Amadeo de Souza-Cardoso's sequence - a single chapter in a chromatic story told across many works.
