Description Costas 2012-05-07 21:33:47 UTC
EOG version displays the blue color almost as violet. See attached a comparation between same image displayed with EOG and Shotwell.
Comment 1 André Klapper 2012-05-08 07:43:33 UTC
Attachment is missing. 
Do you use any color calibration under "System Settings > Hardware > Color"?
Comment 2 Costas 2012-05-08 21:00:06 UTC
No, it is with the default monitor settings.
Comment 3 Felix Riemann 2012-05-10 15:29:49 UTC
Please check with

xprop -root | grep _ICC

Just to be sure.

If you don't have a profile set, it would be nice if you could attach your comparision and (if possible) the original image so we can try ourselves.
Comment 4 Felix Riemann 2012-05-10 15:35:27 UTC
Please also post the output if you run with the following env vars set:

No difference in output if variables are set.

Whoops, I was actually interested in the console output that eog makes in that case. ;)

But that's no problem, because...

... you do have a profile set. If you had no profile set, the grep wouldn't show an _ICC_PROFILE entry.
Comment 10 Felix Riemann 2012-11-11 17:14:59 UTC
There seems to be some problems with some autogenerated ICC profiles.

Reassigning to gnome-settings-daemon to check if there might be a problem with profile generation in the color management plugin.

There are at least three other bug reporting unexpected colors with the autogenerated(?) profiles, where dropping the profiles restored the output: #681460, #670836, #681460.

This seems to have hit several people using Ubuntu:

Felix, see -- can you follow those instructions (and ask anyone affected to do the same please) so we can do something smarter for GNOME 3.10. Thanks in advance.

We now ignore invalid EDID blobs.
