Charles William Wyllie is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #443124, registers at 2.4% - sparse enough to feel like a deliberate surprise. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Charles William Wyllie's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
