Art Brut keeps values measured and balanced, a hallmark of tonal restraint. Yellow, ochre, sienna: warm hues deployed as the palette's primary energy. All colours lean toward grey, building depth through value rather than colour punch. #2F436B functions as the palette's exclamation mark: highest chroma, lowest percentage (2.5%). The full value range is 56 units: broad enough to build convincing three-dimensional form.
