Pieter Casteels II distributes its values across the middle register, creating harmony without high contrast. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 4.9% is devoted to #E7E5D1, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 66 units: broad enough to build convincing three-dimensional form. In the context of Pieter Casteels II's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
