Firefox-19.0 Colour Management

Firefox detects since version 17.0 the Linux system profile, which is a great improvement for the operating system. While colour conversions on all platforms still default to on for ICC tagged content, they can be enabled for all other colours. Untagged colours will then default to sRGB instead of omitting monitor compensation for them. To do so go to the famous about:config URL and change gfx.color_management.mode from “2″ to “1″. Then use the installed CMS, e.g. on  KDE KolorManager, to set a system monitor profile, and it will be detected after restarting Firefox.

For Android there is no CMS available. That means the ICC monitor profile must be set manually or sRGB will be assumed instead. The settings name in about:config is gfx.color_management.display_profile. Enter into this string the file name with full path, if you are on Android. That procedure is somewhat inconvenient compared to desktops. However the OpenICC group has published some specifications for implementation. This might be even possible for students inside the rewarding Google Summer of Code 2013 program.

For comparison, the Chrome web browser does support colour management on some desktop versions but unfortunately not on Android.

The below false colour test image should look correctly with ICC profile enabled browsers. Look at the colour gradients and then at the colour names and compare.
