Charles-Amable Lenoir distributes its values across the middle register, creating harmony without high contrast. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #5C5030, registers at 11.5% - sparse enough to feel like a deliberate surprise. The value range spans 66 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Charles-Amable Lenoir's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
