Henri Martin occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #6B773C, registers at 8.0% - sparse enough to feel like a deliberate surprise. 40 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Henri Martin's full range of palettes, group 10 represents one movement in an ongoing chromatic dialogue.
