Light floods Apollonio Domenichini; the palette keeps values pale and airy across its range. Apollonio Domenichini builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The dominant colour, #A1B8C3, takes 29.5% of the total area, establishing the overall mood before any other hue is introduced. The highest-chroma note - #67533D - appears at just 6.5%, deployed as a precision accent against the quieter ground. Value range is moderate at 53 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 1 sits within the larger chromatic argument that Apollonio Domenichini's complete body of work advances.
