Light floods A.Y. Jackson; the palette keeps values pale and airy across its range. A.Y. Jackson 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. #CEA55E functions as the palette's exclamation mark: highest chroma, lowest percentage (6.0%). At 72 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of A.Y. Jackson's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
