Marie Spartali Stillman 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. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #E1D2B9, registers at 10.0% - sparse enough to feel like a deliberate surprise. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. The palette is a signature: Marie Spartali Stillman's particular sense of value, warmth, and colour weight made legible.
