Values in Paul Jacoulet tilt decisively toward white, giving the palette its luminous character. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. A single dominant - #E2DACA at 32.1% - sets the character of the whole composition. #52408D delivers the chromatic peak at only 2.4% - a small shot of colour with outsized visual impact. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light Paul Jacoulet preferred, made measurable.
