Bart van der Leck is strongly light-biased - shadow is suggested rather than declared. 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. Bart van der Leck gives 38.7% of the composition to a single #E1D6C0 - a decisive chromatic anchor. #BB4D40 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.8%). The palette spans 54 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Bart van der Leck's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
