Eugène Grasset keeps values measured and balanced, a hallmark of tonal restraint. 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. #EF4127 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.1%). A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Taken together, these qualities constitute Eugène Grasset's chromatic voice - distinctive enough to be read across an entire body of work.
