Erich Buchholz distributes its values across the middle register, creating harmony without high contrast. Erich Buchholz orchestrates warmth above all else - reds, ambers, and siennas take the lead. All colours lean toward grey, building depth through value rather than colour punch. #2B2A2B at 33.2% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. Only 6.8% is devoted to #AC733C, yet that small allocation delivers the palette's entire chromatic tension. Value range is moderate at 53 units - enough contrast for legibility, not so much as to fragment the tonal unity. In the context of Erich Buchholz's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
