Darkness anchors Francesco Ribalta; light is rationed, creating dramatic contrast rather than open air. 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. 27.2% of the palette belongs to #171412, a concentration that makes it the unmistakable visual centre. #893319 delivers the chromatic peak at only 2.9% - a small shot of colour with outsized visual impact. A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Together these qualities place Francesco Ribalta firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Palette 4 sits within the larger chromatic argument that Francesco Ribalta's complete body of work advances.
