The value structure of Hugo Simberg is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The chromatic peak belongs to #7D4120, and at 3.1% it dominates, not decorates. The full value range is 65 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 3 of Hugo Simberg's sequence - a single chapter in a chromatic story told across many works.
