Mid-key values give Poster Art Realism its characteristic quietness - nothing blazes, nothing disappears. The palette 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. At 27.8%, #877C66 functions less as a colour accent and more as a complete atmospheric environment. The highest-chroma note - #B1A25C - appears at just 6.3%, deployed as a precision accent against the quieter ground. At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
