Eero Järnefelt is high-key - luminous, open, and weighted toward light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #D9E2DE claims 35.5% of the surface, functioning as the work's tonal foundation. #C4B799 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.8%). The value range spans 63 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Eero Järnefelt's full range of palettes, group 7 represents one movement in an ongoing chromatic dialogue.
