The value structure of George Dunlop Leslie is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #8A6840 delivers the chromatic peak at only 6.4% - a small shot of colour with outsized visual impact. 56 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode George Dunlop Leslie's instinctive sense of how much of each quality the eye can hold.
