The value structure of Jan van Kessel the Elder is mid-key: quiet, controlled, and cohesive. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 1.3%, #E35126 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 61 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is the light Jan van Kessel the Elder preferred, made measurable.
