The currently selected label is displayed in the orange accent colour. This is either the label for the currently selected image / box or the label that will be applied to the next box that is created.
Toggling label visibility:
- Tap on the eye button to toggle the visibility of boxes with that particular label. This is only applicable when using an object detector.
