Mid-key values give Jacob Grimmer its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #584527, registers at 11.3% - sparse enough to feel like a deliberate surprise. Value range is moderate at 51 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 4 of Jacob Grimmer's sequence - a single chapter in a chromatic story told across many works.
