Nicolas Poussin distributes its values across the middle register, creating harmony without high contrast. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #9C7E58 - appears at just 9.0%, deployed as a precision accent against the quieter ground. At 55 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Palette 4 sits within the larger chromatic argument that Nicolas Poussin's complete body of work advances.
