Hugo Simberg distributes its values across the middle register, creating harmony without high contrast. Temperature is cool-dominant, with blue and green families claiming the largest areas. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. At 10.7%, #3C3A1B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 59 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 4 of Hugo Simberg's sequence - a single chapter in a chromatic story told across many works.
