What unites the illustration movement is as much chromatic as stylistic; this palette traces that unspoken agreement. illustration sits in the centre of the value range, lending the palette a sense of even, sustained light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #745D44 delivers the chromatic peak at only 9.1% - a small shot of colour with outsized visual impact. The value range spans 63 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Applied to contemporary work, these proportions immediately evoke the illustration register.
