Frantisek Kupka is high-key - luminous, open, and weighted toward light. Warm hues command this palette; Frantisek Kupka favours the reds, oranges, and yellows of firelight and earth. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. A single dominant - #F5E8D9 at 27.6% - sets the character of the whole composition. #351A1D functions as the palette's exclamation mark: highest chroma, lowest percentage (3.9%). 68 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Palette 1 sits within the larger chromatic argument that Frantisek Kupka's complete body of work advances.
