Henri Fantin-Latour dwells firmly in the shadows, with no more than a whisper of light. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 34.8%, #170F11 functions less as a colour accent and more as a complete atmospheric environment. The highest-chroma note - #713829 - appears at just 4.0%, deployed as a precision accent against the quieter ground. A value spread of 64 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. In the context of Henri Fantin-Latour's full range of palettes, group 17 represents one movement in an ongoing chromatic dialogue.
