John Singer Sargent keeps values measured and balanced, a hallmark of tonal restraint. Warmth dominates - the palette of John Singer Sargent leans heavily on the yellow-orange-red arc of the colour wheel. Mid-range chroma keeps the palette grounded - colourful but not strident. The highest-chroma note - #CF823B - appears at just 3.3%, deployed as a precision accent against the quieter ground. A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 23 sits within the larger chromatic argument that John Singer Sargent's complete body of work advances.
