Henri Martin occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Henri Martin balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #A56F54, registers at 4.3% - sparse enough to feel like a deliberate surprise. Value range is moderate at 42 units - enough contrast for legibility, not so much as to fragment the tonal unity. In the context of Henri Martin's full range of palettes, group 9 represents one movement in an ongoing chromatic dialogue.
