Aluminum that's been bath-grown an oxide skin and dyed before sealing. Reds, blues, greens, golds — saturated where the part stays out of UV, gentler outdoors. Anodized iPods, brand-color bicycle stems, ano-jewelry, the colored bezel on a chronograph.
Type II Class 2 per MIL-A-8625 dyed in the same dye-immersion + nickel-seal sequence as black anodize. Color comes from the dye, not the metal — the 1–25 µm oxide layer is colorless. UV-stability ranges widely: Sandoz Sanodal Deep Red and Clariant Anaplast Bright Blue hold their color for years outdoors; cheap dyes drift in months. Light alloys (6061 / 6063) dye most uniformly; copper-rich alloys streak. Hard-anodized (Type III, see hardcoat) takes color too but reads darker because the thicker oxide tints down to bronze.
character — saturated when fresh, slightly satin (substrate-dependent), warm-cool depending on hue and seal chemistry.

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.
