John Singer Sargent sits in the centre of the value range, lending the palette a sense of even, sustained light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #BA864B - appears at just 4.2%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 64 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 6 of John Singer Sargent's sequence - a single chapter in a chromatic story told across many works.
