Cimabue is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. 30.9% of the palette belongs to #F5FAFA, a concentration that makes it the unmistakable visual centre. The most saturated colour, #D5C399, is reserved to 5.9% of the surface, where it acts as a focal punctuation. A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Cimabue's sequence - a single chapter in a chromatic story told across many works.
