Michel-Barthelemy Ollivier occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Michel-Barthelemy Ollivier tilts toward cool - blues and silver-greys carry the structural weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 4.3%, #8C7831 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The palette spans 50 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Michel-Barthelemy Ollivier's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
