Light floods Charles Rennie Mackintosh; the palette keeps values pale and airy across its range. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #AB927B functions as the palette's exclamation mark: highest chroma, lowest percentage (11.9%). The full value range is 56 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Charles Rennie Mackintosh's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
