Please see https://github.com/cncf/artwork/ where we have the TUF and Notary logos. We prepare artwork in 3 formats (PNG/SVG/AI), 3 layouts:
- Horizontal (also known as landscape format).
- Stacked (which is closer to square).
- Icon (which does not include the name and is square).
And 3 versions (color/black/white). So, that's at least 27 versions of most logos.
