Compass mark & wordmark
A rounded dark square with a compass rose — north half in bearing red like every
real compass needle, south half in Silent Mode acid green, softened east-west arm so the N-S
bearing dominates. Plus theseus.x with the .x TLD picked out in acid. The
mark alone works when you have no room for the wordmark; the full lockup is the default choice
everywhere else.
Wordmark, monochrome
Uses currentColor, inherits from the
surrounding text. Print, embossing, single-colour merch.
Avatar & favicon
Square icons for social profiles, Nostr, GitHub, and browser tabs.
Avatar
Square profile picture. Social platforms apply their own round mask; the corner radius keeps the compass intact when clipped.
Favicon
Rounded browser-tab icon. Scales down to 16×16 cleanly; used on every Theseus.X page.
Social banner
1200×630 (OpenGraph / Twitter Card canonical). Composition survives aggressive centre-cropping — the compass mark and tagline both stay visible even after Facebook and Discord chop the sides.
Colour palette
Silent Mode family colours. Dark chromes are the default; acid green is the accent that signals "this is Theseus.X", and bearing red is reserved for the compass mark's north triangle — never used for links, buttons, or generic UI accents.
Typography
System font stack, so nothing needs to load and every OS renders the wordmark in the same family the reader is used to.

.x is a <tspan fill="#d6ff3d"> —
don't render the whole word in acid. The compass north triangle is the only place
bearing red appears; don't add red anywhere else in the chrome.Usage & trademark
These files are the marks of Theseus and Silent Mode, not open-licensed artwork: the code is MPL-2.0, the name and the compass are reserved, and the trademark note says what that allows. Use them to refer to Theseus in third-party tools that integrate with Theseus.X (BCNR name explorers, wallet bridges, blog posts, review sites), never as your own mark. Keep the compass proportions intact and don't recolour the acid to a similar-but-different green — palette drift is what makes brands look untrustworthy over time.
- Do use the mark to indicate "opens in Theseus" or "supports BCNR".
- Do shrink to the favicon at 16×16 — the SVG scales cleanly.
- Do use the monochrome logo where the acid green would clash.
- Don't imply endorsement of a specific product without asking.
- Don't ship a fork, a product or a name under this name or mark — a fork is welcome under its own.
- Don't stretch, skew, or re-tint the compass.
- Don't introduce a second accent colour — acid green is the only one.
