Jacob van Ruisdael sits in the centre of the value range, lending the palette a sense of even, sustained light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #594928 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.7%). A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Jacob van Ruisdael's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
