Cinnamon desktop color shift

I have a question about Darktable in Linux Mint Cinnamon and the color blue.

All settings are standard, but when editing, the flowers are purple instead of blue. After exporting to JPG, the color reverts to blue.

This issue is specific to Cinnamon, as everything works fine in the Xfce environment.

I don’t understand why this is happening. I haven’t made any changes to my Darktable settings.

Most probably a display colour profile issue, and/or you have some gamut check indicator enabled. You should open a new topic, though: this thread is for the release announcement, not for general tech support. @paperdigits @afre , could you please split this out to a new topic?

Sorry for the mistake. We’re closing this thread.

A good way to test if it is a display issue (wrong display profile or some darktable indicator turned on) is loading a known-good JPG into darktable (that won’t be processed at all by default). If that has the shift as well, then you’ll know it’s not a processing but a display (profile) issue. Once you have the result of that test, we can help you further.

A screenshot of the issue would be useful.

A photo in jpg format loaded into Darktable is displayed in purple instead of blue.

The same photo is displayed correctly in Pix.
So the problem concerns DT. Except that I haven’t changed anything in the settings.

Not so sure. Maybe Pix is just not color managed? Or the display profile set in dt on your side is wrong?

So either something is wrong with your Cinnamon setup, or your darktable setup is wrong in a way that doesn’t show up under Xfce. As you keep on claiming you didn’t change a thing, without providing more specific information (like your darktablerc, or the requested screen shot), that’s about all I can say…

I am just a regular computer user and don’t know much about software, so I can’t give you the exact settings for Darktable.
I am currently switching from Windows 10 to Linux and am looking for the right version for me.
I have noticed that Darktable and Rawtherapee work best in the MX KDE environment.
I am also testing Mint XFCE and Cinnamon, and that is where I noticed the incorrect blue color when editing in Darktable.
Perhaps the program was installed with errors. However, after reinstalling, the problem still persists.
This is not a big problem for me, as I will be using MX kde or Mint XFCe.
Nevertheless, I asked on the forum, because maybe I will find the cause and learn something new.

But you never answer our questions. You seems to draw conclusions without strong data. What you should do:

  • Send over a photo where it seems wrong to you
  • Post a screenshot of what you call the good version
  • Post a screenshot of what you call the wrong version

And then we can help.

Sure. As soon as I get to a computer, I’ll share the photo and screenshots.

Darktable comes with a tool called darktable-cmstest. Open a terminal (console), and run it, then submit its output. It would be great if you could paste the output here between 3 ` marks, like so:

```
paste the output here
```

Also, what version of darktable? Native package (deb or from a repository), snap, flatpak, appimage? That influences how you launch darktable-cmstest.

Version 5.2.1
flatpack



Loaded Lumix style for better visibility

Please run this command under both environments:
flatpak run command=darktable-cmstest org.darktable.Darktable
and paste the output as requested above.

What do you mean?

You seem highly confused about what is needed. Clearly we cannot help with just that.

I guess the camera-specific processing style. Is that the case, @Damian_J ?

Probably so, but we need untouched edit for the two envs otherwise we cannot tell what’s wrong. And furthermore as I have asked we need the picture (RAW).

And of course what you’ve asked @kofa (the darktable-cmstest).

Double-check your Color Profile system settings in your desktop environment. I recently realized that, sometimes, automatically generated color profiles get applied, with potentially weird results. This recently drove me insane.

It is a RAW file, but after loading the file, I enabled the camera style, which provides a much brighter and clearer image.
