Chromium nitride PVD — a hard ceramic film, color reads bronze / pewter / smoke depending on stoichiometry. Sits between TiN's gold and DLC's deep black on the PVD color spectrum. Premium plumbing fixtures, watch cases that want gunmetal, hardware that wants 'industrial luxury' without going to gold or black.
Cathodic-arc or sputter deposition of chromium nitride. Stoichiometric Cr₂N reads silver-gray; CrN reads pewter / bronze; over-stoichiometric CrN₁₊ shifts toward gold. Film thickness 1–4 µm, hardness 1500–2200 HV. Common decorative-PVD line carries TiN gold, ZrN champagne, CrN pewter, TiCN warm bronze, AlTiN charcoal-anthracite (near-black), DLC black as color options on the same hardware. Where the design wants 'gunmetal' or 'pewter' or 'smoke gray,' CrN is usually the spec; where the design wants 'rose gold' or 'champagne,' CrN gets co-deposited with copper (CrCN) for warmer tones, or TiCN (titanium carbonitride) is specified directly for the warm-bronze register.
character — pewter / bronze / smoke, between gold and black on the PVD spectrum, gunmetal-luxe register.

Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, with cost-over-volume curves, trade-off profiles, equipment-tier filters, and second-life paths layered onto the data 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.
