The value structure of Guy Rose 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. The saturated accent, #C0B575, registers at 7.7% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 61 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. These proportions encode Guy Rose's instinctive sense of how much of each quality the eye can hold.
