The palette of Johann Koler sits in the lower register of the value scale - dense, contained, and weighted. Yellow, ochre, sienna: warm hues that Johann Koler deploys as the palette's primary energy. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The dominant colour, #130D0A, takes 25.7% of the total area, establishing the overall mood before any other hue is introduced. The most saturated colour, #D7A66C, is reserved to 2.7% of the surface, where it acts as a focal punctuation. The value range spans 59 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Johann Koler's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
