The value structure of Biedermeier is mid-key: quiet, controlled, and cohesive. Temperature reads distinctly warm: the reds and earth tones carry the compositional weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #A16343 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.4%). Value range is moderate at 52 units - enough contrast for legibility, not so much as to fragment the tonal unity.
