From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Can someone explain what this really does ? The article is very lacking.
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.
No calibration yet.
You don't need a protocol for profiling, it's merely a nicer user experience if you have one.
I still wish we had display calibrators that operated over DDC on linux T.T well, ddcui helps, but it's not automagic T.T
Oh yeah I've seen issues in KDE Wayland for it lately, namely on brightness. It's gone since.
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.
If you're on Plasma, setting the color profile to "built-in" might be all you need to make them reasonably match
I'm using Plasma, and I'm having trouble finding where it is. Where would I look for this setting?
It's in the display settings
I know this is probably not a solution to your problem, but maybe:
