John Atkinson Grimshaw occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #815126, registers at 11.3% - sparse enough to feel like a deliberate surprise. The full value range is 61 units: broad enough to build convincing three-dimensional form. Taken together, these qualities constitute John Atkinson Grimshaw's chromatic voice - distinctive enough to be read across an entire body of work.
