Google calendars can have color labels to make their events visually distinct and easy to organize.
Skylight calendar events are also color coded. Events in your Calendar are color coded according to the Profile (or Profiles) the events are associated with.
When events are synced from Google to Skylight, Skylight preserves the color coding used with Google, but doesn't have a good way to automatically assign synced events to the correct Profile or Label. Skylight will create new Profiles for each of the color coded calendars, with a hexcolor name (for example: #33ff66).
To better organize your calendars, color coded calendar Profiles can be merged with existing Profiles and Labels in the Skylight Mobile App.
For more about merging Profiles and Labels, please see: Profiles and Labels.
