Leonardo da Vinci distributes its values across the middle register, creating harmony without high contrast. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #608497, is reserved to 5.8% of the surface, where it acts as a focal punctuation. A value spread of 69 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Taken together, these qualities constitute Leonardo da Vinci's chromatic voice - distinctive enough to be read across an entire body of work.
