ICC profiles are used to color manage digital images. Each device that you use to view or print your images has a unique ICC profile. When you edit an image in Photoshop, you can apply an ICC profile to ensure that the colors are rendered accurately on that device.
PRO TIP: When editing ICC profiles in Photoshop, it is important to be careful not to accidentally delete or change important settings. If you are not familiar with ICC profiles, it is best to seek help from a professional before making any changes.
To edit an ICC profile in Photoshop, go to Edit > Color Settings. In the Color Settings dialog box, select the profile that you want to edit from the Profile drop-down menu. You can then make changes to the settings for that profile.
When you’re finished making changes, click OK to apply the changes and close the dialog box. Your ICC profile will now be updated with your changes.
