Values in John Collier rest in the mid-range - neither dramatically lit nor steeped in shadow. John Collier keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. Only 12.0% is devoted to #91652D, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 68 units: broad enough to build convincing three-dimensional form. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. Palette 6 sits within the larger chromatic argument that John Collier's complete body of work advances.
