''ColorSync Utility'' is software that ships with [[Mac OS X]]. It is used for management of color profiles and filters used in Apple's [[PDF]] [[workflow]], or applying filters to images and PDF documents.<ref>{{Cite web |title=Modify image colours in ColorSync Utility on Mac |url=https://support.apple.com/en-au/guide/colorsync-utility/csyncad0012c/12.0/mac/14.0 |access-date=2023-12-14 |website=Apple Support |language=en}}</ref>

The interface is composed of two parts: the document browser and the utility window. The document browser lets you zoom in and out of an image or apply a Filter to it. The utility window has several options: Profile First Aid, Profiles, Devices, Filters and Calculator.<ref>{{Cite web |title=How to use ColorSync Utility to assign color profiles in OS X |url=https://www.cnet.com/tech/computing/how-to-use-colorsync-utility-to-assign-color-profiles-in-os-x/ |access-date=2023-12-14 |website=CNET |language=en}}</ref>

* ''Profile First Aid'' allows you to repair ColorSync color profiles so they conform to the [[International Color Consortium]] specification.

* ''Profiles'' allows you to browse the profiles installed on your system, grouped by location, class or space, and graphically compare any two profiles.

* The profile map is displayed as a rotatable, scalable 3D object and can be plotted in [[CIELAB]], [[CIELUV]], [[CIE 1931 color space|Yxy]], [[Yuv]] and [[CIE 1931 color space|CIEXYZ]].

* The ''Devices'' section allows you to see a list of all registered ColorSync devices such as your displays and printers, and see what ColorSync profile is applied to each one. You can also override the default setting.

* The ''Filters'' section allows you to build and modify PDF filters that are available to the rest of the operating system. Each filter can be set to appear in one of three domains: Application, PDF Workflows, and Printing.

Filters set to Printing will appear in the drop-down menu under the "Save as PDF..." button in the standard Mac&nbsp;OS&nbsp;X print dialog box. Filters set to PDF Workflow will appear in the [[Quartz (graphics layer)|Quartz]] Filters drop-down menu in the ColorSync section of a print dialog box. The default filters that ship with Mac&nbsp;OS&nbsp;X are:

* Black & White

* Blue Tone

* Create Generic PDFX-3 Document

* Gray Tone

* Lightness Decrease

* Lightness Increase

* Reduce File Size

* Sepia Tone.

User-created filters can have color management, image effects, PDF retouch, domain selection and comments.

The ''Color Management'' section allows assigning a profile, choosing a default profile, [[rendering intent]], converting to a profile or intermediate transform.

The ''Intermediate Transform'' section allows adjustment of brightness, tint, hue, saturation, bilevel (high pass filter) or profile assignment, to either [[grayscale]], [[RGB]] or [[CMYK]], or all data in the file. This can be applied to either text, graphics, images or shading.

Complex filters can be created by stacking multiple effects. Any changes made to the PDF file can then be saved as a new PDF file.

''Calculator'' can convert between [[RGB]], [[CMYK]] and other color value schemes, and features an interactive color-picker for identifying a color on the screen, duplicating a feature of another bundled utility, ''[[Digital Color Meter]]''.
