Values in Briton Riviere rest in the mid-range - neither dramatically lit nor steeped in shadow. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The highest-chroma note - #4C3616 - appears at just 7.6%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 60 units of the value scale - a span that creates natural depth. The combination of mid-to-high key, balanced temperature, and elevated chroma is characteristic of Impressionist observation: light broken into its component hues. In the context of Briton Riviere's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
