John White Alexander occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The highest-chroma note - #977630 - appears at just 11.2%, deployed as a precision accent against the quieter ground. The full value range is 65 units: broad enough to build convincing three-dimensional form. 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 White Alexander's complete body of work advances.
