Louis Glackens is high in key: pale, luminous, and filled with optical air. Louis Glackens tilts toward cool - blues and silver-greys carry the structural weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #B49F6E, is reserved to 9.8% of the surface, where it acts as a focal punctuation. The full value range is 59 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 1 sits within the larger chromatic argument that Louis Glackens's complete body of work advances.
