The high-key values of Henri Matisse give it an effulgent, almost bleached quality. Henri Matisse builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 34.1%, #F1EFE8 functions less as a colour accent and more as a complete atmospheric environment. #C46755 delivers the chromatic peak at only 7.5% - a small shot of colour with outsized visual impact. The value range spans 69 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Henri Matisse's complete body of work advances.
