John Atkinson Grimshaw sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. John Atkinson Grimshaw gives 25.9% of the composition to a single #564A2B - a decisive chromatic anchor. At 4.8%, #998B35 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. John Atkinson Grimshaw's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
