Henri Regnault sits in the centre of the value range, lending the palette a sense of even, sustained light. Warmth dominates - the palette of Henri Regnault leans heavily on the yellow-orange-red arc of the colour wheel. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #966B50, registers at 7.6% - sparse enough to feel like a deliberate surprise. A value spread of 57 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. In the context of Henri Regnault's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
