I just updated to Mavericks and noticed that the Skype icon in my dock is a deeper blue than it was before, and it looks like there's more contrast in general. Did the new version of OS X modify the color profiles?

I do web design work, so color accuracy is pretty important for me. I got used to the old colors, so this change might be problematic for me.

Did OS X change the color profiles? Is there a way to turn them back?

  • I know that this is probably silly, but I seriously want to know: what's the use of all this color profile uptightness for web design work? User's devices are all uncontrolled anyway, so whatever painstaking care one puts in presumably goes all to waste. Of course for print and generic work I fully understand the need. – Kuba Ober Oct 23 '13 at 18:20
  • It's not because my colors are perfectly calibrated or anything, or I want everything to look perfect everywhere (at least that's me). It's just that I've been working with certain colors for a year and them being changed makes it harder for me to recognize them and use them. – Gabriele Cirulli Oct 23 '13 at 21:43

Looking at the standard profiles included with Mac OS X suggests two profiles have changed:

  • Generic Gray Gamma 2.2 Profile.icc
  • Generic Gray Profile.icc

Profile md5 Signatures

The profiles were compared using a simple file content check using md5:

cd /System/Library/ColorSync/Profiles
md5 *

OS X 10.8

MD5 (AdobeRGB1998.icc) = dea88382d899d5f6e573b432473ae138

ColorSync Utility

You can use the included ColorSync Utility to examine the ColorSync profile in use by your displays.

Applications > Utilities > ColorSync Utility.app

Using this utility you can compare profiles with your last OS X 10.8 back-up and, optionally, restore any custom profiles you created. Restore easy access to prior profile by placing them within the /Library/ColorSync/Profiles folder.

ColorSync Utility.app

  • Also, if you don't have administrator access, ~/Library/ColorSync/Profiles works as well. – SilverWolf Sep 29 '17 at 20:46

Mine is absolutely different. Warm colors are very over-saturated. I am in design as well and it's a very frustrating 'update' from Apple.

    This is an answer, not a comment. The question is whether color profiles changed. This user reports that yes, color profiles changed. – Daniel Oct 23 '13 at 15:53

My custom profiles were deleted and the system was reset to the default profile - you'll have to recalibrate your screen.

Mine were reverted to a default, but my original profiles were there and listed in System Preferences -> Display -> Color.

Yes, Apple changed the color profile in Mavericks. You can see the difference immediately. The black is not black, it's more like dark brown.

There is one way to get best color accuracy. You have to you any display calibrate app like SuperCal. I also do some web design and photo manipulation work and it's necessary that you calibrate the screen.
