Pieter Saenredam is high in key: pale, luminous, and filled with optical air. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #E6E8D7 at 27.2% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #CEBF94 - appears at just 8.4%, deployed as a precision accent against the quieter ground. At 57 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Pieter Saenredam's sequence - a single chapter in a chromatic story told across many works.
