Gustave Caillebotte 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. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. #273B2B is not a small accent - at 6.6% it qualifies as a major presence and gives the palette its chromatic identity. From deepest dark to palest light, the palette traverses 67 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. Palette 11 sits within the larger chromatic argument that Gustave Caillebotte's complete body of work advances.
