Creating a Custom Color Label Set
Lightroom includes three default Color Label Sets: Bridge Default, Lightroom Default, and Review Status. However, you are not limited to working with just these three presets. You can edit them and save as many custom color label-presets of your own as you like.
Edit and Save a Color Label Set
Choose Color Label Set from the Metadata menu and select Edit.
Choose a Color Label Set from the Preset drop-down list.
Enter new text in the respective color fields.
From the Preset menu, choose Save Current Settings as New Preset.
Enter a name for the preset and click Create.
Lightroom adds the new set to the Color Label Set Preset list.
