Vincent van Gogh sits in the centre of the value range, lending the palette a sense of even, sustained light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #A66F44 - appears at just 4.6%, deployed as a precision accent against the quieter ground. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 13 sits within the larger chromatic argument that Vincent van Gogh's complete body of work advances.
