Values in John Frederick Lewis rest in the mid-range - neither dramatically lit nor steeped in shadow. Temperature is cool-dominant, with blue and green families claiming the largest areas. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The highest-chroma note - #D8B67B - appears at just 9.4%, deployed as a precision accent against the quieter ground. The full value range is 68 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 Frederick Lewis's complete body of work advances.
