Mid-key values give William Logsdail its characteristic quietness - nothing blazes, nothing disappears. William Logsdail builds on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 12.4% is devoted to #524721, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 71 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that William Logsdail's complete body of work advances.
