label.save()
# change its color:
label.color = '#112233'

Delete a label for a project:

project.labels.delete(label_id)
# or

Manage labels in issues and merge requests:

# Labels are defined as lists in issues and merge requests. The labels must

                         'description': 'issue description',
                         'labels': ['foo']})
