ref:colour_tx=* describes the color of the text of the reference for highways and public transport lines and networks.
Usage
The key ref:colour_tx=* is used to define the colour of the text displayed inside a reference shield. It is used in combination with ref:colour=* (which defines the background colour of the same shield).
The key ref:colour_tx=* is used to ensure the map accurately represents the official operator's branding. While many editors (like iD) automatically choose black or white text based on background contrast, this manual tag is necessary in several cases:
- Corporate pairs: When a network is defined by two specific corporate colours that must always go together.
- Official identity over legibility: When the operator uses a specific combination that differs from automated defaults.
While traditionally used in the road network of Spain, it is also used for public transit networks to ensure that brand-specific route labels are rendered with the correct contrast and corporate identity.
Values
Values are typically expressed as:
- Hexadecimal color codes: e.g., #FFFFFF (White) or #000000 (Black).
- Standard CSS color names: e.g., white, black.
