Michel-Barthelemy Ollivier occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. A single dominant - #FEFEFE at 27.0% - sets the character of the whole composition. The most saturated colour, #B9AD81, is reserved to 6.3% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 73 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Michel-Barthelemy Ollivier's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
