Mid-key values give Francesco Sleter its characteristic quietness - nothing blazes, nothing disappears. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 5.0%, #7F451F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 69 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Francesco Sleter arrived at this balance through long practice; the palette carries the weight of that experience.
