This page is the canonical reference for the Casa Hacker brand: logo, symbol, colours, typography, sub-brands and usage rules. The documentation of components — ready-made HTML, CSS and patterns — is canonical in the full design system.

technical contexts: favicon of the platforms (Cockpit, Cockpit MCP, casahacker.org, Administration MCP) and app/PWA icon of the tools. It does not replace the H symbol.

Keep at least 1× the height of the H of clear space around the logo. No element — text, image or border — may enter that zone. Below the minimum size, use the H symbol alone.
New code uses the brand names below. The semantic roles (primary, secondary, surface-*) still exist in global.css — the equivalence table is just below the swatches.
| brand token (official) | semantic equivalent | note |
|---|---|---|
| hacker-green | primary-container (#32FA96) · inverse-primary (#00E384) | primary (#006D3C) is the AA version for text |
| electric-violet | secondary-container ≈ (#C18EFE) | secondary (#7645B0) is the AA version for text |
| brand-blue | tertiary-container ≈ (#BFDFFF) | tertiary (#3C6282) is the AA version for text |
| deep-obsidian | on-background · on-surface | same value (#1A1C1A) |
| clean-white | ≈ surface (#FAF9F6) / surface-container-lowest (#FFFFFF) | surfaces use the surface-* ramp |
| muted-stroke | ≈ outline-variant (#BACBBB) | low-relief outlines |
A new layer on top of the design system, which defines colour by sub-brand (programme). On the by-area surfaces — the four cards on the homepage, the menu markers — the rule is: the area sets the colour of the card; the sub-brand sets the colour of the initiative chip inside it. Always with the text pairing indicated (AA contrast).
IBM Plex Sans
Headings, paragraphs and everything that is actually read. Weights 400, 600 and 700, with fluid scaling (clamp) on displays and headlines. Self-hosted — no font leaves a CDN.
IBM Plex Mono
Labels, chips, metadata, navigation and microcopy in uppercase with wide tracking. It is the “terminal” voice of the identity — never used for running text.
Casa Hacker owns the marks “Casa Hacker”, “PerifaImpacto”, “Minas em Tech”, “Inclusão Tech” and “Hackerclubes” — so that people can tell the difference between official projects and independent projects that use our technologies, infrastructure, space, investment or any other kind of support.
1 · free use
Mentioning Casa Hacker in texts and presentations, linking to our sites, saying you used our space, explaining that your initiative uses a technology of ours.
2 · use by agreement
Formally supported projects may use “Supported by Casa Hacker” and the “Supported/Accelerated Initiative” seal — keeping their own visual identity and the nature of the relationship clear.
3 · prohibited use
Using our marks in a product, company or domain name; selling products bearing the marks; suggesting a partnership that does not exist; modifying or combining the logo.
The Outros Futuros 2026 campaign is the first physical piece derived from the design system: one T-shirt print and six posters, each in SVG and PDF. The PDFs are vector files at real physical size — the print opens at 280 × 370 mm, the posters at A3 — and the type is already converted to outlines: no file asks for IBM Plex by name, so there is no font for the printer to substitute. The canonical source is the casahacker/tshirt-outros-futuros-2026 repository, whose CI rejects any colour outside the palette and any stroke below the 0.8 mm screen-printing floor. The pieces are in Portuguese; the notes below say what each one reads.
The pieces are released under CC BY-NC-ND 4.0 ↗: download, print and distribute each piece whole and unaltered, crediting Casa Hacker, for non-commercial purposes. Use of the trademarks remains governed by the three rules above.
The casahacker/design-system repository is the canonical source of components, patterns, dataviz and print pieces — HTML + CSS with no build step, open to contribution.
