The value structure of Graham Bell is mid-key: quiet, controlled, and cohesive. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Mid-saturation across the board: the palette has colour character without chromatic excess. The saturated accent, #CBAC55, registers at 6.4% - sparse enough to feel like a deliberate surprise. At 44 units across the value scale, the palette keeps contrast readable without letting it dominate. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. Palette 3 sits within the larger chromatic argument that Graham Bell's complete body of work advances.
