Constantin Daniel Rosenthal 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. At 3.2%, #7C2E12 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 62 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 Constantin Daniel Rosenthal's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
