Merged yesterday to the Chromium open-source codebase for the Google Chrome web browser is Wayland color management support! Linux users running on Wayland will now be able to enjoy high dynamic range (HDR) video playback within Google's web browser.

For the past month [1]Wayland color management had been under review for the Chrome/Chromium browser to allow rendering to HDR surfaces. That code was finally merged on Monday.

[2]This commit introduced the Wayland color management support that has been tested using the KDE Plasma 6.4 desktop on Wayland. There still is a remote kill switch should Google end up needing to disable the functionality due to issues.

"[Wayland] Support color management protocol

This change adds support for color-management-v1. This enables rendering to HDR surfaces on supported platforms. I've verified HDR video playback is working on KDE Plasma 6.4.2. A WaylandWpColorManagerV1 feature flag is added and enabled by default, which can be used as a remote kill switch in case we need to disable the feature. Once this lands, the old zcr_color_manager_v1 can be removed."

Users will be able to find this support in Chrome 141 due out by the end of September.
