Louis Valtat keeps values measured and balanced, a hallmark of tonal restraint. Louis Valtat 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. Only 4.0% is devoted to #854E27, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 62 units: broad enough to build convincing three-dimensional form. 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 Louis Valtat's sequence - a single chapter in a chromatic story told across many works.
