Mid-key values give Sidney Richard Percy its characteristic quietness - nothing blazes, nothing disappears. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #372D1E, registers at 11.1% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 75 units of the value scale - a span that creates natural depth. Palette 5 sits within the larger chromatic argument that Sidney Richard Percy's complete body of work advances.
