Preview+El Capitan = color management bug?

Apple leadership and product teams do not participate in these open, user-to-user support communities. If you have detailed, constructive product input to share with Apple, then do so through the appropriate channel — macOS product feedback.

You should confirm the ColorSync profile used by the image in the Preview Inspector. If it is not what you intended, then choose the proper display profile from View menu : Soft Proof with Profile sub-menu.

afaik, apple's bug report system isn't open (meaning you can't see posted bugs by others, only by yourself) - There is a community called Open radar where they are posting some apple bugs, but not all bugs are posted there (you have to do it manually, and I didn't)

I have a similar issue on Sierra with a new Late 2016 MacBook Pro. Everything looks fine in the apps I make stuff in (Sketch, Photoshop, After Effects), but when they're saved, or a screenshot is pasted into something like Slack, the colors get less saturated, and a little yellow.

For kicks I took a screenshot of a screenshot of a screenshot a few times over and the image basically turns grayscale.

This is a massive problem for me as I do visual design work for a living.

Wondering what the deal is.

Hi arlorose, yes - frustrating to say the least. Here's a well documented discussion of the problem: http://apple.stackexchange.com/q/271825/216401

I would recommend you read through it, then get your p's and q's sorted out to clearly state a bug report to Apple.

Good luck!

I have this problem too! OMG, Apple, FIX IT!

I'm upgrading computer after this summer, don't let it be Windows! Get bugs checked out, I don't care about the darn night mode and emojis!

Any one found a solution to this infuriating problem? How can Apple claim their OS is great for graphic design when ColorSync can't handle non-Apple colour profiles correctly! Like many Mac users, I've calibrated my displays using a Spyder device only to find that ColorSync screws up the black point. 😠

Also found this thread on the same problem: https://hub.displaycal.net/forums/topic/dark-images-in-mac-photos-preview-with-d isplaycal-generated-profile/

Has anyone solved the problem? The year 2017 ends. And the problem remained! What do Apple engineers do?

I have established by experience that only the color profile created on Matrix (not LUT) work well in all Apple program. But in the profile based on the matrix is less visible details in the shadows. So the question remains open. I want to use the LUT profile.

Obvioisly Apple don’t care. We just sold all of our iMacs and MBPs because they left the creatives for the common people, easy money for them. I have only an iPhone left, but thats about to change as-well.

Sorry Apple. But thanks for the last money I got from warranty case, now I’m building a $4000 rig.

You might want to submit a bug report to Apple: https://developer.apple.com/bug-reporting/

did you find a solution @diegotrystero ??

I've got a similar post here (with example) after doing lots of tests myself: Re: wrong colors in preview.app. Preview also does not seem to save the color profile info when I change them individually either. Apple, we really need this fixed!

i have same color bug in this apps (((

This color bug in ALL system apps in Os Sierra too.

Preview, Safari , Final Cut Pro X.

Hello,

Exactly the same problem here, did you ever find a solution?

I've tried producing v2 & v4 profiles.... It looks to be a gamma problem.

Thanks
