What is ColorSync Utility?
Get consistent colors across devices
Use color profiles to make sure the colors in your images appear the same on all your displays—and when you print.
Find color values
Use the Calculator to get the values for a color on your screen—right down to the pixel. You can also get the values for a color in another installed color profile to make sure the color appears the same on all your devices, including printers.
