The value structure of Alfred Sisley is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. #777141 delivers the chromatic peak at only 2.7% - a small shot of colour with outsized visual impact. 57 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. These proportions encode Alfred Sisley's instinctive sense of how much of each quality the eye can hold.
