Louis Anquetin is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The chromatic peak belongs to #D99F43, and at 53.8% it dominates, not decorates. The value range of 36 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Louis Anquetin's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
