The value structure of Johann Koler is mid-key: quiet, controlled, and cohesive. Warm hues command this palette; Johann Koler favours the reds, oranges, and yellows of firelight and earth. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The saturated accent, #964B1E, registers at 3.7% - sparse enough to feel like a deliberate surprise. At 68 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 5 of Johann Koler's sequence - a single chapter in a chromatic story told across many works.
