Issue
The text for on-call coverage substitutions is difficult to read in the legacy on-call calendar, due to a low contrast color combination.
Cause
The span color of the on-call coverage for another roster member is set by the system property 'com.snc.on_call_rotation.cover.color'. This property accepts hexadecimal code values, for example, if you would like these spans to show yellow, you can change the value to something like #FFFF00.
The documentation page below lists all the available system properties for the On-Call Scheduling module:
