Johan Fredrik Eckersberg occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #79673A, registers at 11.2% - sparse enough to feel like a deliberate surprise. The full value range is 55 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Johan Fredrik Eckersberg's complete body of work advances.
