Low-key values are the structural spine of Frederick George Cotman, giving it gravity and atmosphere. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. All colours lean toward grey, building depth through value rather than colour punch. Only 4.8% is devoted to #92692F, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 58 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This tonal restraint is characteristic of the Frederick George Cotman approach: colour serves light, not the reverse. Palette 6 sits within the larger chromatic argument that Frederick George Cotman's complete body of work advances.
