Values in Frantisek Kupka rest in the mid-range - neither dramatically lit nor steeped in shadow. Frantisek Kupka orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #DFC8A3, is reserved to 10.3% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 55 units of the value scale - a span that creates natural depth. Palette 4 sits within the larger chromatic argument that Frantisek Kupka's complete body of work advances.
