Wayland color management

The second has the problem that the colorspace has to be communicated somehow. Creating our own format can result in really stupid mistakes and requires new tools and libraries, reusing an existing standard also has drawbacks (which standard to choose, which subset of the standard is valid for the use-case).

No solution seems particularly good.

I disagree. All operating systems that have color management use ICC profiles for this purpose. So all applications that are written for a color managed operating environment make use of ICC profiles to communicate the display device response. There is zero reason to create something new here.
