Light floods Louis Hayet; the palette keeps values pale and airy across its range. Louis Hayet tilts toward cool - blues and silver-greys carry the structural weight. All colours lean toward grey, building depth through value rather than colour punch. At 36.4%, #E6E5DE functions less as a colour accent and more as a complete atmospheric environment. The most saturated colour, #3B4492, is reserved to 3.5% of the surface, where it acts as a focal punctuation. Spanning 50 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 1 sits within the larger chromatic argument that Louis Hayet's complete body of work advances.
