John French Sloan occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The dominant colour, #A99F71, takes 26.1% of the total area, establishing the overall mood before any other hue is introduced. At 2.4%, #AC6A39 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 56 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 John French Sloan's complete body of work advances.
