We’ve just recently landed new features to Firefox’s color management library QCMS to add support for a subset ICC v4. If you don’t know what Color Management is just think of this way: Recording devices such as high end camera, scanners and display devices such as monitors, scanners can have different color spaces. Color management is the process of mapping color from the input color space to the output space. The changes to QCMS in particular bring support for Color Lookup Tables.
The changes are in the nightly build and can be enabled by setting the preference |gfx.color_management.enablev4| and restarting your browser. You can confirm that the feature is enabled by visiting Is your system ICC V4 ready. At this point we encourage everyone to help test the feature and would like to collect feedback in bug 488800.
