Henry Gibbs keeps values measured and balanced, a hallmark of tonal restraint. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Henry Gibbs gives 29.8% of the composition to a single #30302F - a decisive chromatic anchor. #C4A038 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.4%). The full value range is 55 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. Taken together, these qualities constitute Henry Gibbs's chromatic voice - distinctive enough to be read across an entire body of work.
