Mid-key values give cityscape its characteristic quietness - nothing blazes, nothing disappears. Built on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 9.5%, #CAB592 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 57 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
