Low-key values are the structural spine of Jan van Huysum, giving it gravity and atmosphere. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. #1C1B16 at 32.5% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #88693A - appears at just 3.1%, deployed as a precision accent against the quieter ground. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate. This tonal restraint is characteristic of the Jan van Huysum approach: colour serves light, not the reverse. This is palette 3 of Jan van Huysum's sequence - a single chapter in a chromatic story told across many works.
