Low-key values are the structural spine of Henri Fantin-Latour, giving it gravity and atmosphere. Henri Fantin-Latour balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Henri Fantin-Latour gives 34.0% of the composition to a single #1B1714 - a decisive chromatic anchor. Only 3.2% is devoted to #E4D7B3, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 67 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This tonal restraint is characteristic of the Henri Fantin-Latour approach: colour serves light, not the reverse. This is palette 10 of Henri Fantin-Latour's sequence - a single chapter in a chromatic story told across many works.
