Left: Firefox (correct color). Right: Chromium (wrong color)

I am using Plasma 5 and EIZO CG275W with hardware calibration.

After noticing that my photos look too saturated compared to the way I see them
in Windows, I found this info:

https://userbase.kde.org/Color_Management

Then I installed Kolor-manager and Oyranos CMS from
http://download.opensuse.org/repositories/multimedia:color_management/openSUSE_Tumbleweed/multimedia:color_management.repo

After restarting KDE I went to systemsettings (the one for KDE4 where I could
find the Color Management menu) and set the proper ICC profile I already had
for my monitor. Restarted KDE again.

After opening the same page with photo in the Firefox and Chromium - Firefox
displays the image with correct colors and Chromium still shows it as if
nothing has changed (e.g. wrong colors). Also when switching profiles in
kolor-manager I can actually see how color changes in Firefox but in Chromium
it stays the same.

I also notice that the official Google Chrome browser has the same issue as
Chromium. But it happens only in Linux. Testing with
chromium-48.0.2564.109-832.1.x86_64 installed from network:chromium and Firefox
44.0.2 from the official repo.

Clarification: I also have a second EIZO monitor but it is turned off (not used
during the test). Just mentioning that because it is visible in kolor-manager
as :0.1 L885.

Just for info: In Windows everything checks when testing the Win versions of
Google Chrome and Firefox.
