Light floods John Duncan; the palette keeps values pale and airy across its range. John Duncan tilts toward cool - blues and silver-greys carry the structural weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #8AA1B9 delivers the chromatic peak at only 4.4% - a small shot of colour with outsized visual impact. The value range of 51 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. John Duncan's palette 2 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
