Heinrich Lefler is high in key: pale, luminous, and filled with optical air. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #E4E48A claims 28.0% of the surface, functioning as the work's tonal foundation. At 8.2%, #918F58 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 63 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 1 sits within the larger chromatic argument that Heinrich Lefler's complete body of work advances.
