As an exciting late addition to the [1]GNOME 48 codebase ahead of its stable release in mid-March, the Wayland color management "wp_color_management_v1" protocol support has been merged!

With the [2]Wayland Protocols 1.41 release earlier this month having [3]the color management protocol for HDR support under Wayland, a late addition for Mutter with GNOME 48 is supporting this wp_color_management_v1.

Sebastian Wick opened the merge request for Mutter last week and this morning it's been merged. In the comments to the merge request, it mentions it's been successfully tested with the likes of work-in-progress GStreamer code for HDR10 content playback. It's also been tested with GTK4, Quake II RTX, and other sotware.

See [4]the merge ticket for all the details on this now-merged wp_color_management_v1 support in Mutter for GNOME 48. This goes along with other recent [5]GNOME 48 HDR support bits that have landed in recent weeks. It's looking like GNOME 48 will be playing nicely with HDR displays if all goes well.
