Values in Johann Koler rest in the mid-range - neither dramatically lit nor steeped in shadow. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #A89843, is reserved to 9.8% of the surface, where it acts as a focal punctuation. The value range spans 62 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. 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 Johann Koler's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
