The pencil, the Bull, the mark.

How coldchainOS looks and sounds: signatures, colour, type, icons and voice. Use the files unmodified to refer to the project.

Signatures

Two elements: the Bull for stories, the mark for everything small.

  • Always spell it coldchainOS: lowercase “coldchain”, uppercase “OS”, one word.
  • Don’t stretch, rotate, recolour the horns, add glow, or place the mark over busy imagery.
  • Below 40 px use the favicon geometry, not the detailed mark.
The coldchainOS Bull: charcoal fur, crystalline ice-blue horns, platinum aviators and an ice-blue suit

The Bull

Storytelling, not decoration.

The Bull carries the large, narrative moments: heroes and social. The mark distils his horns and aviators into flat geometry for navigation, favicons and small spaces. Use the supplied files; don’t redraw, mirror or crop the horns.

Colour

Midnight ground, ice-blue signal, platinum restraint.

  • Midnight navy#06142APage background
  • Surface#0D1F3ACards and elevated panels
  • Deep charcoal#1B2129Neutral dark surface
  • Ice blue#8FCFF5Primary accent

  • Muted text#9AAABDSecondary text on dark

Type

Archivo for display. Inter for everything you read or measure.

Both are open-licensed (SIL OFL 1.1) and self-hosted. Numbers use Inter with tabular figures so columns align, always with units and the operation that produced them.

Does the cold chain pencil?

Evidence in. Assumptions visible. Math you can check.

Icons

Eight original icons. One stroke weight.

  • Cold storage facility
  • Community
  • Dataset
  • Energy
  • Evidence
  • Local compute
  • Refrigeration
  • Underwriting

Voice

Experienced. Direct. Evidence-led.

Every statement is one of three kinds, and we say which.

  • Measured. Observed or reported, with source and date.
  • Illustrative. An example built to show a calculation. Labelled every time.
  • Planned. Work we intend to do. “Planned”, never “now supports”.
