George Barbier keeps values measured and balanced, a hallmark of tonal restraint. George Barbier builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 4.9% is devoted to #D4882D, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 71 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light George Barbier preferred, made measurable.
