Michel-Barthelemy Ollivier occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. All colours lean toward grey, building depth through value rather than colour punch. Only 9.4% is devoted to #7A6A4A, yet that small allocation delivers the palette's entire chromatic tension. Spanning 44 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. 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 3 represents one movement in an ongoing chromatic dialogue.
