Henri Martin sits in the centre of the value range, lending the palette a sense of even, sustained light. Henri Martin builds on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #969DCB, registers at 8.0% - sparse enough to feel like a deliberate surprise. Spanning 42 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. This is palette 5 of Henri Martin's sequence - a single chapter in a chromatic story told across many works.
