Mid-key values give Henryk Siemiradzki its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #CFC466, registers at 2.5% - sparse enough to feel like a deliberate surprise. A value spread of 63 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. The palette is recognisably Henryk Siemiradzki's own: particular in its temperature, chroma, and the economy of its brightest note.
