Darkness anchors George Romney; light is rationed, creating dramatic contrast rather than open air. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 2.4%, #B27B4C carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 57 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of George Romney's full range of palettes, group 16 represents one movement in an ongoing chromatic dialogue.
