Brand
Tevrin’s mark is a hexagon of six segments. The six segments are the six lifecycle phases, and the gaps between them are the approval gates.
Logo files
| File | Use |
|---|---|
| Lockup, light | Mark and wordmark on light backgrounds |
| Lockup, dark | Mark and wordmark on dark backgrounds |
The files live in docs/v6/brand/. The README shows the light lockup with a #gh-light-mode-only fragment and the dark lockup with #gh-dark-mode-only, so the logo follows the theme the reader has chosen on GitHub. Other Markdown viewers (such as an editor preview) ignore the fragments and show both lockups.

Usage rules
- Put no text on the gradient.
- Use the gradient sparingly: the mark and a few highlights.
- Use the mono variant where one colour is needed, such as print, a favicon or a single-colour badge.
- Pick the light or dark lockup to match the background. Don’t recolour or stretch the mark.
- Keep clear space around the mark of at least the width of one segment.
- Warning colours are never used for text.
- Status badges pair a colour with a dot and a label, so colour is never the only signal.
- Write the name as “Tevrin”. Describe the code as “source available on GitHub”, never “open source”.
