Heinrich Deiters is high-key - luminous, open, and weighted toward light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #8E6C5D functions as the palette's exclamation mark: highest chroma, lowest percentage (3.5%). From deepest dark to palest light, the palette traverses 59 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 1 sits within the larger chromatic argument that Heinrich Deiters's complete body of work advances.
