Raphael Kirchner is high in key: pale, luminous, and filled with optical air. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Raphael Kirchner gives 33.7% of the composition to a single #EFDDBB - a decisive chromatic anchor. The highest-chroma note - #A98349 - appears at just 6.0%, deployed as a precision accent against the quieter ground. At 62 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 17 sits within the larger chromatic argument that Raphael Kirchner's complete body of work advances.
