Mid-key values give John Singer Sargent its characteristic quietness - nothing blazes, nothing disappears. 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 highest-chroma note - #979CC0 - appears at just 3.9%, deployed as a precision accent against the quieter ground. 64 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of John Singer Sargent's full range of palettes, group 22 represents one movement in an ongoing chromatic dialogue.
