Values in J.M.W. Turner rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #563718 delivers the chromatic peak at only 6.8% - a small shot of colour with outsized visual impact. The full value range is 57 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 12 sits within the larger chromatic argument that J.M.W. Turner's complete body of work advances.
