John Frederick Lewis sits in the centre of the value range, lending the palette a sense of even, sustained light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 6.1% is devoted to #7E6147, yet that small allocation delivers the palette's entire chromatic tension. Spanning 51 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 5 sits within the larger chromatic argument that John Frederick Lewis's complete body of work advances.
