Caspian, in the right shape.
Logos, colours, type, the social kit and the design language behind the app. Everything here is free to use when you write about Caspian, link to it or ship something that works with it.
Badge, mark and wordmark.
Slate badge
The single-colour badge for print, monochrome contexts and the installer. Slate disc, white waves.
Mark alone
The waves without the disc, for favicons at tiny sizes, watermarks and places that already have a shape.
Wordmark
Badge plus the name in Inter Semibold. One version per ground; don't rebuild it from parts.
Badges
The three marks Caspian puts in the address bar, on the tab and in site info. They are part of the product, not the brand: show them only when explaining verified sites, and never as decoration.
The site is on Caspian's signed list and this is the genuine address.
An official government site, verified the same way and given its own colour.
Rose means a verified political campaign or party.
Give it room. Keep it legible.
- Clear space around the badge is the height of the big wave, on every side. Nothing else goes inside it: no text, no other logos, no edge of the canvas.
- Minimum size is 24 px on screen and 8 mm in print for the badge. Below 20 px use the mark alone, which is what the favicon does.
- Wordmark: the gap between badge and name is fixed at 0.55 badge widths; the name is set in Inter Semibold at 1.2 badge heights.
Light ground, ink text, three accents.
The colours the app uses for its channel dot and installer ribbon.
Inter for words, JetBrains Mono for numbers.

The interface is one surface that flows.
Against the window edge, so the blob takes the card's corner.

A light accent gradient rises from the bottom.
Small rounded cards that fade in below the control.
The lattice lights up in the accent colour under the cursor.
Do and don't.
- Use the gradient badge on white or the ground colour, with clear space around it.
- Use the white badge on dark or coloured grounds.
- Keep the badge and the wordmark exactly as supplied; scale them together.
- Write the name as “Caspian”, capital C, no “Browser” unless the context needs it.
- ×Don't recolour the badge, swap the gradient direction or add an outline.
- ×Don't stretch, rotate, skew or add effects (shadows are fine on the promo images only).
- ×Don't place the gradient badge on a busy photo without the white ring behind it.
- ×Don't rebuild the wordmark with a different typeface or a different gap.
- ×Don't use the waves as a pattern or crop the disc.
