Charles-Philippe Lariviere distributes its values across the middle register, creating harmony without high contrast. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #C45927, is reserved to 3.6% of the surface, where it acts as a focal punctuation. The value range spans 69 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-Philippe Lariviere's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
