Mid-key values give Jacob van Ruisdael its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 8.1%, #C8BFA1 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 64 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Jacob van Ruisdael preferred, made measurable.
