Over on the Collabora blog, Pekka Paalanen [1]writes about adding color management and high dynamic range (HDR) support to the [2]Wayland display server protocol. X11 already has support for color management tools and workflow, but not HDR, and Wayland currently doesn't support either, but Paalanen and others are working to change that. " As color management is all about color spaces and gamuts, and high dynamic range (HDR) is also very much about color spaces and gamuts plus extended luminance range, Sebastian [Wick] and I decided that Wayland color management extension should cater for both from the beginning. Combining traditional color management and HDR is a fairly new thing as far as I know, and I'm not sure we have much prior art to base upon, so this is an interesting research journey as well. There is a lot of prior art on HDR and color management separately, but they tend to have fundamental differences that makes the combination not obvious. "

Paalanen: Developing Wayland Color Management and High Dynamic Range
Wayland might be a chance to finally sort out this mess. I've got two monitors that support basic 30bpp input, one a decade old now, and it's never been safe to use on X because so many things make the assumption that every drawable is 24bit (some may even be assuming it can't be *lower*, but I don't want to check).
Of course, graphics drivers missing 30bpp support for years didn't help…

Nice to see someone finally working on colour management in Wayland!
