Louis-Francois Cassas is strongly light-biased - shadow is suggested rather than declared. Louis-Francois Cassas builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #605432 delivers the chromatic peak at only 3.9% - a small shot of colour with outsized visual impact. Value range is moderate at 53 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Louis-Francois Cassas's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
