/* Terza Studio, direction B: Überdruck.
   Two process inks, cyan and yellow, printed over each other. The overlap is green.
   Colour only lives in the overprint and in thin yellow marks. Everything else is ink on paper.
   Rules: cyan and yellow are never text colours (too little contrast on paper). Radius 0. No shadows. */
