--- Comment #8 from Kai-Uwe Behrmann <ku.b at gmx.de> ---
I had to remove many of the Scarse profiles from Krita due to colorimetry bugs.

OpenICC has a set of profiles for many purposes. A wide gamut profiles in this
collection
are LStar-RGB, which is similar to  ECIv2-RGB but licensed like all others
under libpng/zlib.
compatibleWithAdobeRGB1998.icc is a replacement for AdobeRGB. AdobeRGB is not
freely distributable.

More infos on the OpenICC wiki:
http://www.freedesktop.org/wiki/OpenIcc#Profiles_for_standard_print_condition_and_their_licenses
http://www.freedesktop.org/wiki/OpenIcc/ProfilePackages
Source Package:
http://sourceforge.net/projects/openicc/files/

As these ICC profiles are required by Oyranos, they are already packaged by
many distributions. Debian has them as well in the icc-profiles package.

A real replacement for ProPhotoRGB is not easy. ProPhotoRGB uses a gamma of
1.8, which is not so good for gamma 2.2 and sRGB systems. A replacement needs
some discussion on OpenICC.
