Using colors defined for a different area feels like a beige flag for me since for example "late" has nothing to do with "full" but I believe that having a shared color palette would be beneficial. There is also slight precedence with cancel not getting its own dedicated color:
Line 94 in 09f577c
In an ideal world, I would like INFO, WARNING, CRITICAL (or similar wording) colors defined that both status and occupancy inherit from but that feels like too big of a breaking change for agencies that customized the colors. I also don't know if there is a migration process for things like this.
Alternatives considered:
- Define own colors for occupancy status
- Pros: Not connected to status so variable naming isn't confusing
- Cons: Color palette drift between status and occupancy (although if don't want shared palette, this is a feature)
- Create new abstraction level but leave
brand-*status colors are legacy code
- Pros: Gets the higher level of abstraction that both status and occupancy can inherit from
- Cons: Legacy code has to be maintained
This is all under the assumption that a shared color palette is beneficial. I would be open to implementing 1 or 2, but they were bigger changes so I just biased towards the simplest implementation for now.

Deviations from original issue spec:
formatOccupancyreturns'LIGHT' | 'MEDIUM' | 'FULL' | nullinstead of{ level, label, icon }. The label and glyphs live inOccupancyPip, so the formatter doesn't call translations. I followed a similar pattern to how bus status is reported.Things to note/open questions:
