Logos

Badge, mark and wordmark.

Gradient badge

The primary mark. Sea-to-teal disc, white highlight, the double wave. Use it on light grounds and in the app.

Slate badge

The single-colour badge for print, monochrome contexts and the installer. Slate disc, white waves.

White badge

White disc, slate waves, for dark or coloured grounds where the gradient would fight the background.

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.

Verified #3b82f6

The site is on Caspian's signed list and this is the genuine address.

Government #7c5cff

An official government site, verified the same way and given its own colour.

Political #e0486a

Rose means a verified political campaign or party.

Clear space & size

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.

Colours

Light ground, ink text, three accents.

Click a swatch to copy its value. The interface is grey and white; colour is reserved for state and for the brand gradient, which only appears on the badge, the primary button and highlighted words.
Release channels

The colours the app uses for its channel dot and installer ribbon.

Inter

UI and headlines. Weights 500 and 600 only; 400 for body copy. Headlines are tracked tight, −0.02em to −0.03em, and set with balanced wrapping.

JetBrains Mono

Versions, hashes, shortcuts and anything a person might copy.

⌘T⌘⇧AF120.1.2sha256:9f3a…c1e2

The app itself uses the system UI font (Segoe UI Variable, SF Pro, Cantarell); Inter matches its proportions on the web.

Liquid UI

The interface is one surface that flows.

Caspian's design language. Controls are pills, panels have 12 px corners, and nothing appears from nowhere: a popover grows out of the button that opened it. The button becomes a round blob that joins the card through a waisted stem with concave fillets, a metaball join like a drop of water meeting a puddle.
Main menu, right edge

Against the window edge, so the blob takes the card's corner.

The badge in the address bar becomes the blob; the stem waists into the card.

The join, exactly

  • Card: rounded rectangle, radius 12, top edge at y = neck.
  • Blob: circle, diameter 28, centred at (anchorX, 14), exactly over the button that opened it.
  • Stem: 0.62 × blob wide, from the circle down to the card top.
  • Fillets: concave, radius 9 where the stem meets the card; radius 3 where it leaves the circle.
  • Fill white, stroke 1px rgba(21,22,28,.1), shadow 0 14px 24px ink at 16%.
  • When the blob would pass the card's corner, it takes the corner: the right side of the circle continues straight down as the card edge.
