Il Sassetta (Stefano di Giovanni) works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #DCD6C8 claims 36.3% of the surface, functioning as the work's tonal foundation. Only 7.6% is devoted to #3C3223, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 56 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 3 of Il Sassetta (Stefano di Giovanni)'s sequence - a single chapter in a chromatic story told across many works.
