Jean-Charles Langlois 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. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #C09B63 - appears at just 6.9%, deployed as a precision accent against the quieter ground. Spanning 48 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. 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 Jean-Charles Langlois's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
