Support for color management has been merged into Wayland's Weston compositor.
The Wayland color management work done by Richard Hughes and talked about for the past month
has finally landed in mainline Weston. The code
allows for ICC color profiles to be specified within the Weston configuration file or a CMS implementation to be loaded from a pluggable module.
This new feature will be present in Wayland 1.2
for those concerned about color accuracy.
