I can reproduce. Peter, can you please look at it?
Comment 2 Piotr Popieluch 2015-11-13 08:39:16 EST
When I set gfx.color_management.mode to 0 it shows the colors correctly. The default is 2. 

I've checked on the ubuntu system and it also has the setting set to 2, but there it does show the image colors correctly.
Comment 3 Piotr Popieluch 2015-11-20 06:39:51 EST
The colors now look different, but still not correct.


Same version of firefox, I'm trying to check which update might have caused this.
Comment 4 Piotr Popieluch 2015-12-18 17:16:10 EST
ff43 still affected
Comment 6 Martin Stransky 2016-01-04 08:58:30 EST
Seems to be caused by some Fedora Firefox settings, may be caused by image library we use in Fedora. If I built Fedora Firefox with default settings (default mean Mozilla default) the image is show correctly.
Comment 7 Martin Stransky 2016-01-05 15:50:40 EST
it's caused by gfx.color_management.enablev4 which is enabled in Fedora.
Comment 8 Piotr Popieluch 2016-02-17 05:20:50 EST
Tested in FF44 on F23 and can confirm that changing the gfx.color_management.enablev4 setting to false shows the image how it is intended to be.

Could the default be changed?
Comment 9 Fedora End Of Life 2016-11-24 08:23:06 EST
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. 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bug reports from releases that are no longer maintained.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 '23'.

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 23 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 2016-12-20 10:49:39 EST
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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

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