Brand Kit
Logos, colours, type, and assets for representing B3 — for partners, press, and anyone building in the ecosystem.
✦ SERIOUS PLAY ✦ ONCHAIN ARCHITECTS ✦
Everything here is cleared for partner, press, and ecosystem use — take what you need without asking first. Every preview links the real file on cdn.b3.fun, so what you download is what we use. The CDN serves files inline, so open the link and save from there.
Brandmark
The full lockup: wordmark, positioning line, and the stack it names. Use it when B3 needs to introduce itself — a title card, a deck cover, a partnership announcement. Everywhere else, the wordmark alone is enough.
Logo
The B3 wordmark. Use the SVG wherever you can — the PNG is a fallback, not a preference.
Working on a light surface and need the wordmark in brand blue, or on a dark one and need a knockout we don't list here? Ask — we'd rather send the right file than watch one get recoloured by hand.
Using the mark
Colours
One blue, quiet everything else. B3 blue is the only accent — the neutrals do the structural work, and a surface where three things compete for attention has no accent at all.
text#2450FF
Primary actions, links, live state.
text#11172F
Dark surfaces, headings on light.
text#D9D9D9
The signature canvas — b3.fun's own stage.
text#C9C8D0
Panels and dividers on gray.
text#535C89
Secondary text and quiet links.
text#9496A8
Captions, labels, table headers.
Typography
Interface, headings, body, and data. 55 Roman for text, 65 Medium for anything that carries weight. Tracking stays at 0 — only small uppercase labels get wide tracking.
Technical tags, diagram labels, small system text. Used sparingly, never for body copy.
Both are commercially licensed, so we don't redistribute the font files — license them directly from the foundries above. If you can't, this stack degrades honestly:
cssbody { font-family: "Helvetica Neue LT Pro 55 Roman", "Helvetica Neue", Helvetica, Arial, sans-serif;}
https://cdn.b3.fun/fonts.css still serves the previous typefaces (Neue Montreal, Calibre, Pack). It is kept alive for older properties — don't wire it into anything new.
Assets
The dimensional B3 — extruded, isometric, and coined. These carry the brand where a flat wordmark can't.
Backgrounds
Full-bleed brand surfaces for slides, covers, and headers.
More in the same set: b3-bg-3.png and b3-bg-5.png.
Motion
Movement is part of the brand — systems coming online, not decoration. Fast state changes, subtle transitions, no bounce, and always respect prefers-reduced-motion.
The full-length brand background loop is a large file — link it rather than embedding it: b3-bg-animation.mp4 (~17 MB).
Co-branding
Partnership lockups follow one shape: each mark in its own dotted ring, separated by ×, at equal weight. Nobody's logo gets top billing.
Contribute to the B3 brand
Let's build B3 together — we welcome creators, artists, developers, and everyone else who wants to make something with it.
Reach out if you've built something for the B3 community, or if you need an asset that isn't here.
