John Atkinson Grimshaw 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. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The highest-chroma note - #E4D1AA - appears at just 5.4%, deployed as a precision accent against the quieter ground. At 68 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 1 sits within the larger chromatic argument that John Atkinson Grimshaw's complete body of work advances.
