Copper (#B87333) is a mid-tone warm shade that appears across 18 master palettes in our corpus, most prominently in the work of Theodore Poulakis, M.C. Escher, and Laszlo Moholy-Nagy and the Baroque tradition. Master painters paired it most often with Smoky black (#100C08), Dark sienna (#3C1414), and Zinnwaldite brown (#2C1608). The combination forms a sun-bleached, daylight chord, built on closely related hues, reads as a unified warm palette, with a sharp light/dark contrast that lets the darker companions read as depth.
