The high-key values of Robert Lewis Reid give it an effulgent, almost bleached quality. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. At 2.4%, #413A21 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 55 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. In the context of Robert Lewis Reid's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
