Gilbert Jackson occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Mid-saturation across the board: the palette has colour character without chromatic excess. The highest-chroma note - #A53D1A - appears at just 3.4%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 60 units of the value scale - a span that creates natural depth. In the context of Gilbert Jackson's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
