Architectural paint comes in five standard sheens: high-gloss (mirror-like, shows every defect), semi-gloss (kitchens / trim), satin / eggshell (most living-room walls), flat / matte (ceilings, hides every imperfection). The chemistry is similar; the sheen comes from the resin / pigment / wax balance. The surface that reads brightest is also the surface that telegraphs every brush stroke.
Sheen level measured by gloss meter at 60° incidence (Gloss Units, GU). Industry conventions: high-gloss ≥85 GU, semi-gloss 35–70 GU, satin 15–35 GU, eggshell 10–25 GU, matte / flat <10 GU. Sheen tuned by pigment-volume-concentration (PVC) and the use of flatting agents (silica, micronized wax) — flatter paints carry more pigment, reflect more diffusely. Resin chemistry orthogonal to sheen — alkyd / acrylic / latex / enamel each available at every sheen. Cleanability roughly tracks sheen: glossier paints scrub better but show every nail-pop and joint-tape lap; flat paints touch up invisibly but mar with the lightest scrub.
character — spectrum from mirror-bright to chalk-matte; paint chemistry tunable across the gloss-meter range.

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.
