Please retest in the Chromium 62 packages I have just pushed as pending updates. It uses gtk3, which may affect the color management.

Okay. If this is happening consistently in Chrome and Chromium, then the bug lies in the upstream codebase. Please file a bug with Google here:

https://crbug.com/wizard

Please put a link back to it there, so I can watch it as well.

Comment 5 Muayyad Alsadi 2017-11-15 07:20:58 UTC
but it might be fedora specific, because fedora is one of the leading distributions to enable color management. most likely upstream assume no color management and do its own.

Comment 7 Muayyad Alsadi 2017-11-27 13:21:45 UTC
they say it's something wrong with the active color profile
I did not changed that, the profile was shipped by fedora

Comment 8 gaxweb 2017-12-01 12:48:24 UTC
FWIW: I've been looking at various browser color management pages on the web¹ on Vivaldi 13, which is based on Chromium 62, and everything seems fine on my end. I have a WCG monitor with a proper color profile that was generated with DisplayCAL and a colorimeter.

In general, using some sort of default color profile defeats the purpose. How likely is it that it'll accidentally match your actual monitor? Might as well use none at all. Actually, that might be what's leading to the color shift you're seeing.

Do you even have color management enabled in Firefox? I think you still have to set up the path to the profile in about:config there. If it's off, then that could explain why the colors differ between browsers now. Chromium is managing colors (according to the bogus profile) and Firefox isn't.

¹ Like: http://cameratico.com/tools/web-browser-color-management-test/ or https://webkit.org/blog-files/color-gamut/ or https://translate.google.com/translate?hl=de&sl=de&tl=en&u=https%3A%2F%2Fwww.fotovideotec.de%2Fbrowser_farbmanagement%2Ffarb-testbilder.html

Maybe check those websites first in both browsers to get a better idea of what the real problem is.

Comment 9 Fedora End Of Life 2018-05-03 08:20:23 UTC
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 10 Fedora End Of Life 2018-05-29 11:45:42 UTC
Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26
is no longer maintained, which means that it will not receive any
further security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
