William James Glackens occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #BE8F63, registers at 8.8% - sparse enough to feel like a deliberate surprise. The value range spans 57 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light William James Glackens preferred, made measurable.
