Light floods William Wyld; the palette keeps values pale and airy across its range. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Only 5.8% is devoted to #B59F86, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of William Wyld's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
