- Under your repository name, click Issues or Pull requests.
- Above the list of issues or pull requests, click Labels.
In the labels list, next to the label you want to edit, click Edit.
- In the text box, type your new label name.
- A color is automatically selected for the label. You can customize this color by editing the hexadecimal number or clicking the refresh button for another random selection.
Click Save changes.
