      Color management ensures accurate and identical color reproduction across display devices. It’s extremely important for artists and designers, and its absence in Wayland is a deal breaker for them.

        I would like to remind everyone that while this extension does not include display response measuring and calibration, they will come later.

        No calibration yet.

      This is the protocol for HDR content. KDE already ships an experimental version of it.

        not just hdr stuff, it’s all color profiling. my old monitor is dark af with wayland because it’s not loading its color profile and i can’t adjust gamma or apply color profiles in settings or with colord like you can in x. i really need this to be able to switch to wayland.

          This protocol isn’t relevant for your compositor to apply an ICC profile. If you’re using KDE Plasma, you can just select it in the settings. I think Sway allows that now too. If you’re on Gnome, you’ll need to wait.

            i’m using kde on endeavouros. when using wayland the color profiles section in settings does nothing. you can go pick a profile and click ok but it just doesn’t load it. colord is the daemon that handles color profiles entirely and that’s what this is about.

              No, colord does not handle color profiles on Wayland. You need to set the profile in the display settings.

              If you have an ICC profile that doesn’t work, please make a bug report about it for KWin.

            I may need to look into this, because the colours between my drawing tablet and main monitor are quite different.

      You can right now. If you are using KDE, it should work with mpv, though you might need to launch it from terminal with a few flags to tell mpv to use HDR.

      If you’re not using KDE, you can launch gamescope with the hdr flag in the tty and have it launch mpv.

      Though I’m not sure any browsers have working HDR. I think Chromium may have some stuff in progress. Gnome Web may get it since WebKit supports HDR and HDR is being worked on for GTK.

          It’s hidden away on Gnome. You need to hit a keyboard shortcut that brings up a special console window then run a command to enable the HDR.

          For better or worse, Plasma has the option prominently displayed in settings.

        Do I have to enable HDR in Plasma settings? Because when I do, and then log out, plasma crashes and I have to log into a different DE and disable HDR in the terminal.

          uh, kinda not really? I mean, you can calibrate your screen to sRGB, if you calibrate it to anything else, every non managed app will completely and utterly break

              what have you used? If you set, say DCI-P3 (not display p3 which uses a similar transfer to 2.2) the issues become evident due to the different transfers that it is quite off.

              if you used something like display p3, then due to the similar transfer, only gamut changes which is a lot harder to notice at a glance

    the Wayland color management protocol might finally be close to merging after four years in discussion.

    But also

    Going all the way back to January 2020

    So really it’s been almost 5 years.

    Let’s hope we can finally get it and move on to any other remaining protocols.

      HDR is new ground on Linux, so it’s understandable it’s taking a while. It requires involvement from all over the graphics stack: graphics drivers, mesa, Wayland protocol, protocol needs to be implemented in compositor, apps need to implement the protocol.
