Jean-Baptiste van Loo occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. 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. #1B1A17 at 31.1% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. #AD7837 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.4%). At 52 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Jean-Baptiste van Loo's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
