Samuel Peploe distributes its values across the middle register, creating harmony without high contrast. Yellow, ochre, sienna: warm hues that Samuel Peploe deploys as the palette's primary energy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #B36D5C - appears at just 3.5%, deployed as a precision accent against the quieter ground. The full value range is 64 units: broad enough to build convincing three-dimensional form. In the context of Samuel Peploe's full range of palettes, group 15 represents one movement in an ongoing chromatic dialogue.
