Domenico Veneziano is high in key: pale, luminous, and filled with optical air. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #EDE8DD claims 34.1% of the surface, functioning as the work's tonal foundation. Only 7.8% is devoted to #ECAA7D, yet that small allocation delivers the palette's entire chromatic tension. 63 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. Palette 1 sits within the larger chromatic argument that Domenico Veneziano's complete body of work advances.
