Low-key values are the structural spine of John Riley, giving it gravity and atmosphere. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The dominant colour, #140F0B, takes 30.1% of the total area, establishing the overall mood before any other hue is introduced. The highest-chroma note - #C39E66 - appears at just 3.6%, deployed as a precision accent against the quieter ground. The value range spans 66 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Together these qualities place John Riley firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Palette 5 sits within the larger chromatic argument that John Riley's complete body of work advances.
