Henry Gibbs occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Henry Gibbs tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. A single dominant - #30302F at 29.8% - sets the character of the whole composition. #C4A038 delivers the chromatic peak at only 1.4% - a small shot of colour with outsized visual impact. 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. This is palette 1 of Henry Gibbs's sequence - a single chapter in a chromatic story told across many works.
