File talk:COVID vaccine passports by state.svg
Colours and NPOV[edit]
Since the subject of passports is sensitive, I recommend that the colour choice be as neutral as possible. For example:
- White/Grey: not applicable
- Dark Grey: banned
- Yellow: partial use
- Magenta: app from cities
- Blue: app from state
The latter three colours shouldn't be too bright, but the colour should be clearly distinguishable. --LABcrabs (talk) 00:23, 2 October 2021 (UTC)
