The XDCCC is a standard part of the ICCCM and describes a convention for
storing CIEXYZ <-> RGB conversion information in the server in the form of
properties on the root window.

Reading the ICC profile file format document ICC.1:2001-12, it appears 
that an ICC color profile could easily be converted into the appropriate 
property contents.

Xlib already supports many color spaces using this information through the
Xcms API.  However, few applications bother to take significant advantage
of this functionality.  I believe this is largely an effect of the strong
pixel-bias for the core graphics operations.  Perhaps libraries layered on
top of the Render extension could expose alternative color spaces to
applications as that rendering model is color based rather than pixel
based.
