Jan Willem van Borselen keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #D6C59C - appears at just 9.8%, deployed as a precision accent against the quieter ground. The value range spans 61 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Jan Willem van Borselen's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
