After five years in the making and over 800 review comments, Wayland's color-management-v1 protocol is merged to the upstream Wayland Protocols repository. The Wayland color-management-v1 protocol allows for Wayland clients (apps / games) to know the color properties of outputs and dealing with the necessary requirements for High Dynamic Range (HDR) display support.
# Wayland Color Management and HDR Design Goals
The goals of Wayland color management and *high dynamic range* (HDR) support protocol extension are:
- Reliably maintain the display server color setup.
- Support professional color managed applications (presentation).
- Support displaying TV broadcasts and other high quality video content.
- Support a wide variety of monitors and application content, including wide gamut and/or HDR.
- Bring basic color management to applications that are not color-aware at all.
- Bring adequate color management to Wayland applications that are color-aware but not color managed.
The protocol support is now merged .
Hopefully 2025 ends up proving to be the year that Linux desktop HDR display support is finally in nice standing.
