Brand

Our brand

CAIRL's visual identity is built for institutional trust. Minimal, precise, and consistent across every surface.

Logo

The [CAIRL] wordmark is set in IBM Plex Mono with a distinctive bracket motif. The brackets sit at 50.2% opacity, framing the letterforms to signal structure and containment.

The wordmark appears in black or white only. Trust Blue is reserved for the [C] favicon and UI accents.

Color

The palette is anchored by Trust Blue — the single interactive color across CAIRL's interface and brand surfaces.

Privacy Black

Foundation Blue

Trust Blue

Clean Slate

Protocol White

Trust Blue (HSL 226 71% 40%) drives buttons, links, and the favicon. Foundation Blue anchors hero surfaces and corporate contexts.

Typography

Two typefaces from the IBM Plex family serve distinct roles across the brand.

IBM Plex Mono

The wordmark typeface. Also used for code blocks, API keys, verification codes, and email aliases.

IBM Plex Sans

The body and UI typeface. Used for all headings, body copy, navigation, and interface elements.

Badge system

The CAIRL trust badge is a horizontal lockup that appears where verification happens. It combines the [C] compact mark with a “VERIFIED” label in a 2px stroke container. The badge ships in Trust Blue for light backgrounds and white for dark backgrounds, at three sizes: large (200×60), medium (160×48), and small (120×36).
