Archibald Thorburn distributes its values across the middle register, creating harmony without high contrast. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #C7AA79, is reserved to 7.8% of the surface, where it acts as a focal punctuation. Value range is moderate at 44 units - enough contrast for legibility, not so much as to fragment the tonal unity. In the context of Archibald Thorburn's full range of palettes, group 7 represents one movement in an ongoing chromatic dialogue.
