The identity
A character of its own
Signal is a two-mode CLI-native system: pale phosphor paper by day, jet-black after dark, and one electric terminal-green that only marks live actions and status. Monospaced headings read like source; the interface reads like tooling that respects the operator.

Who it speaks to
Security platforms, developer tools, CLI utilities, and cybersecurity products — teams shipping to engineers, SREs, and analysts who distrust decorative marketing and trust an interface that behaves like a terminal.
The voice
How it sounds
Terse and technically exact, the way good command output is. State what a thing does, what it returns, and what breaks it. Prefer verbs and specifics over adjectives; a green highlight is reserved for the one live action, never sprinkled for mood.
Art direction
The thinking behind the look
Light mode uses pale phosphor paper (#f4faf5), terminal ink (#0b2110), and deep signal green (#007a2e); dark mode uses jet black (#090909), phosphor white (#e8f8ea), and electric green (#00e05a). Cascadia/Fira Code headings, near-zero radii, and a recurring 3px green status rule preserve the CLI register. Code blocks remain pinned to a dark terminal surface in both modes.
