Samuel Peploe is strongly light-biased - shadow is suggested rather than declared. Samuel Peploe tilts toward cool - blues and silver-greys carry the structural weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #64B6CF - appears at just 3.0%, deployed as a precision accent against the quieter ground. The value range of 52 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Samuel Peploe's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
