Colorsync Utility

What is ColorSync?
(confusing us) is My PEEVE!

Use ColorSync Utility to view installed color profiles on your Mac. When you install devices, such as cameras, displays, or printers, a color profile containing the color capabilities and limits for each device is created. In the ColorSync Utility app on your Mac, click Profiles in the toolbar of the ColorSync Utility window.

  1. You should be able to 'see' it in the Colorsync Utility under Profiles System Rec. ITU-R BT.2020-1, 'Open.' The header is visible there in the new panel as the lead component. I don't know enough to diagnose the header by examining its bits, but that's at least one way to see the 'problem' data.

'ColorSync Profile' = ICC Profile = 'ColorSpace'

I think the color confusion starts by using Apple's 'ColorSync' terminology to encompass 'color management':

  • ColorSync this...
  • ColorSync that...
  • ColorSync calibration...
  • ColorSync Profiles...

I will argue 'ColorSync Profile' is more accurately referred to as an 'ICC Profile' in the field of digital color management.

ColorSync is — merely — a Color Management System (CMS - CMM).
In the case of OS-X, ColorSync also includes an application 'ColorSync Utility.app' used to set up and repair ColorSync issues on the Mac.

Adobe (ACE), Heidelberg, Agfa, and Kodak CMS/CMMs are also individual Color Management Systems (CMS), Color Management Modules (CMM).

LANGUAGE-TRANSLATION ANALOGY

Think of any Color Management System (CMS) as an interpreter of ICC profiles.
The CMS can speak all ICC–profiled languages.

Think of any ICC profile as the written language of each individual, SPECIFIC DEVICE (or ColorSpace) it represents.

Think of your specific monitor ICC profile (MonitorRGB) as an English speaker.

Colorsync Utility

Think of your specific printer/paper/ink ICC profile (TargetICC) as a Spanish speaker.

Think of your Photoshop TaggedFile as a Japanese speaker.

  • 'TaggedFile' represents the Embedded/Tagged colorspace of the open RGB or CMYK file.
  • If you are Embedding/Tagging your RGB files with 'Adobe (1998) RGB' for example:
    TaggedFile = AdobeRGB = WorkingRGB

Further: Enabled Monitor ICC Profile = MonitorRGB

+++++

Think of what the Color Management System does:

MonitorRGB < TaggedFile > TargetICC/CMYK

In other words:
TaggedFile is CONVERTED to MonitorRGB.
TaggedFile is CONVERTED to a specific TargetICC or CMYK.

The CMS takes Photoshop's TaggedFile, Converts (translates) it into MonitorRGB (and onto the screen).

The CMS takes Photoshop's TaggedFile, Converts (translates) it into Specific printer/paper/ink ICC (and onto the print).

Without an interpreter, a CMS — our eyes are explaining our color to an English speaker (MonitorRGB) who explains it to a Japanese speaker (TaggedFile) who explains it to a Spanish speaker (Specific printer/paper/ink) — a screen–to–print match is not gonna happen.

Adobe Photoshop is a color–managed application.

As a color–managed application:
Photoshop's Color Management SystemConverts a Tagged File into MonitorRGB (the monitor's 'calibrated' colorspace) and thereby displays the tagged file's 'true color' through the monitor's 'calibrated' colorspace.

In other words, for example:
In a color–managed application like Photoshop — the enabled Color Management System (CMS):

  1. CMS Converts TaggedFile to MonitorRGB (and onto your screen).
    • If the monitor ICC profile is not accurate, the screen will not be accurate.
  2. CMS Converts TaggedFile to SPECIFIC printer/paper/ink ICC.
    • If the printer/paper/ink ICC profile is not accurate, the print will not be accurate.

Non–color–managed applications do not 'see' the embedded tag, and they do not Convert any color.

• Thus, non–color–managed applications will display a file differently than Photoshop (unless the file was last Saved in the viewing monitor's specific colorspace).

PRINTING WORKFLOW:

At the point we enable any printer color management in our Photoshop printing workflow — ColorSync, printer's Automatic, Photo or Sliders — we lose our 'straight line,' our control of the Conversion: TaggedFile> SPECIFIC printer/paper/ink ICC.

To maintain the strictest control of the MonitorRGB < TaggedFile > PrinterRGB Conversions, see my NoColorAdjustment workflow.

The Mac OS 9 stores ICC profiles in 'ColorSync Profiles' folder, and OS 10 stores them in the Library> ColorSync> Profiles folder, also in the User...Profiles folder.

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.
