Henri Le Sidaner distributes its values across the middle register, creating harmony without high contrast. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is measured and controlled, giving the palette presence without visual aggression. The highest-chroma note - #9C5D3C - appears at just 8.1%, deployed as a precision accent against the quieter ground. Spanning 40 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. Palette 2 sits within the larger chromatic argument that Henri Le Sidaner's complete body of work advances.
