The high-key values of Lancelot-Theodore Turpin de Crisse give it an effulgent, almost bleached quality. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #3A3121 - appears at just 4.5%, deployed as a precision accent against the quieter ground. At 68 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Lancelot-Theodore Turpin de Crisse's sequence - a single chapter in a chromatic story told across many works.
