The value structure of Jacob Grimmer is mid-key: quiet, controlled, and cohesive. Jacob Grimmer tilts toward cool - blues and silver-greys carry the structural weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #C8A066, is reserved to 5.0% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 71 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. The palette is recognisably Jacob Grimmer's own: particular in its temperature, chroma, and the economy of its brightest note.
