William Michael Harnett 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. The dominant colour, #2F2D24, takes 27.3% of the total area, establishing the overall mood before any other hue is introduced. At 4.3%, #9B5B1F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 59 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of William Michael Harnett's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
