George Barbier is low-key throughout, a quality associated with Obsidian Bister - deep shadows dominate the composition. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. George Barbier gives 44.7% of the composition to a single #191202 - a decisive chromatic anchor. The saturated accent, #803C23, registers at 1.4% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 69 units of the value scale - a span that creates natural depth. Together these qualities place George Barbier firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. In the context of George Barbier's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
