Mildred Anne Butler distributes its values across the middle register, creating harmony without high contrast. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight.

Only 8.2% is devoted to #AD7639, yet that small allocation delivers the palette's entire chromatic tension. Value range is moderate at 52 units - enough contrast for legibility, not so much as to fragment the tonal unity. In the context of Mildred Anne Butler's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
