Values in Guillaume Seignac rest in the mid-range - neither dramatically lit nor steeped in shadow. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #463514, is reserved to 10.0% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 64 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. This is palette 5 of Guillaume Seignac's sequence - a single chapter in a chromatic story told across many works.
