John Lavery is strongly light-biased - shadow is suggested rather than declared. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. A single dominant - #CACDD5 at 27.4% - sets the character of the whole composition. The most saturated colour, #4B557B, is reserved to 2.1% of the surface, where it acts as a focal punctuation. Value range is moderate at 52 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of John Lavery's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
