The value structure of Edward Mitchell Bannister is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Mid-saturation across the board: the palette has colour character without chromatic excess. The saturated accent, #33360B, registers at 13.4% - sparse enough to feel like a deliberate surprise. A value spread of 71 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Edward Mitchell Bannister's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
