Edward Hopper keeps values measured and balanced, a hallmark of tonal restraint. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 6.4% is devoted to #C9AA4E, yet that small allocation delivers the palette's entire chromatic tension. 59 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. Taken together, these qualities constitute Edward Hopper's chromatic voice - distinctive enough to be read across an entire body of work.
