The value structure of Walter Sadler is mid-key: quiet, controlled, and cohesive. 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. #625337 claims 210.0% of the surface, functioning as the work's tonal foundation. The saturated accent, #9C7F48, registers at 5.0% - sparse enough to feel like a deliberate surprise. A value spread of 66 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. The palette is a signature: Walter Sadler's particular sense of value, warmth, and colour weight made legible.
