The value structure of Frantisek Kupka is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The most saturated colour, #DD5332, is reserved to 5.1% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 61 units of the value scale - a span that creates natural depth. Palette 9 sits within the larger chromatic argument that Frantisek Kupka's complete body of work advances.
