Compare colour profiles in ColorSync Utility on Mac
Use ColorSync Utility to compare the gamut of two colour profiles.
In the ColorSync Utility app on your Mac, click Profiles in the toolbar of the ColorSync Utility window.
Click a disclosure triangle in the profile list to open a profile group, then select a profile.
Click the pop-up menu in the lab plot, then choose Hold for Comparison.
Click another profile.
The gamut of each profile is displayed. The profile that you held for comparison is lighter than the second profile you clicked.
When you’re finished comparing profiles, click the pop-up menu in the lab plot, then choose Clear Comparison.
