Color of exported images changed due to the switch 'embedded matrix over camera matrix ' for Pentax DNG
I am using DNG as RAW format as Pentax cameras offers this 'natively'.
While working on older images and exporting them again I noticed a change in colors.
previous export: https://homepage.boku.ac.at/kanzian/dt/old.jpg
newer jpg: https://homepage.boku.ac.at/kanzian/dt/new.jpg
Browsing through the commits, I found https://github.com/darktable-org/darktable/commit/37b60adc031a54e7b46998eddf958b69aa7358f5.
'Prefer embedded matrix over camera matrix'
Switching back from embedded to enhanced matrix in the input color module seems to bring back the old colors?
Here are the source files:
What can I do to keep the colors of my images, without switching them back manually?
At least it would be nice to keep them untouched.

- % Done changed from 0 to 50
- Status changed from New to In Progress
1. set "profile" in "input color profile" to "enhanced color matrix"
2. open presets menu for this module, click on "store new preset"
3. enable "auto apply this preset to matching images"
4. click OK

But this will only apply to newly imported images or am I wrong?
Of course I can select all images (only 7000) and set the matrix manually back to enhanced by applying a style.
However, this problem will maybe hit more users once a new stable version will be released.

Yes, this is a known issue in how we handle the colorin settings. Since we don't save the defaults when the defaults change old images get new values. We have half a plan to solve this but it won't be ready for 2.0. Meanwhile we're avoiding adding new matrices to not cause these issues.
