Light floods Philip Wilson Steer; the palette keeps values pale and airy across its range. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #FCFAF2 claims 27.8% of the surface, functioning as the work's tonal foundation. At 2.8%, #BCA87A carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 62 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. In the context of Philip Wilson Steer's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
