Light floods Luc-Olivier Merson; the palette keeps values pale and airy across its range. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 6.0% is devoted to #F6F6FB, yet that small allocation delivers the palette's entire chromatic tension. At 54 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Luc-Olivier Merson's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
