Zirconium nitride PVD — a paler, cooler gold than TiN, approaching white-gold or champagne. Watch bezels, jewelry, eyeglass frames where the warm-gold of TiN reads dated. Same physical category — vacuum-deposited ceramic film — different chemistry, different color.
Cathodic-arc or sputter deposition of zirconium nitride. Film thickness 1–4 µm, hardness 2400–2800 HV, color characteristic pale champagne-yellow (cooler than TiN's warm gold) — band-gap ~2.6 eV. Modern decorative-PVD line carries TiN gold, ZrN champagne, CrN pewter, TiCN warm bronze, AlTiN charcoal-anthracite (near-black), AlCrN dark anthracite as color options on the same hardware platform with gas-mix changes. Where the design calls for 'modern gold' (cooler than yellow gold but warmer than pure white), ZrN is usually the spec.
character — pale champagne, cool warmth, hard, modern-luxury register.

House vocabulary — terms ForMatter uses with intent.
Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, so a student can move from "what is this" toward "what's actually buildable here, now, by me." Part of the renato.design ecosystem — sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Form and matter, inseparable.
Half of teaching materials is teaching how the material is made into the thing. The standard subscription library was always light on that half. The wedge here isn't better samples or a prettier interface — it's treating Process as a peer entity, not a footnote.
