Heinrich Lefler works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. 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 - #B96C3E - appears at just 4.9%, deployed as a precision accent against the quieter ground. The full value range is 81 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 5 of Heinrich Lefler's sequence - a single chapter in a chromatic story told across many works.
