Heinrich Reinhold occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #B7E1E8 functions as the palette's exclamation mark: highest chroma, lowest percentage (7.8%). The full value range is 66 units: broad enough to build convincing three-dimensional form. Heinrich Reinhold's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
