Description Jonathan Liu 2013-05-30 12:37:40 UTC 
The following do not work if Xcms is not enabled in libx11:
- starting xterm and doing ls --color / fails to color code the directories:
  xterm: Cannot allocate color "rgb:5c/5c/ff"
- xsetroot -solid rgb:5c/5c/ff fails with the following error:
  xsetroot:  unknown color "rgb:5c/5c/ff"
- xsetroot -solid rgbi:1.0/1.0/1.0 fails with the following error:
  xsetroot:  unknown color "rgbi:1.0/1.0/1.0"
Comment 1 Jonathan Liu 2013-05-30 12:49:52 UTC 
In particular, it seems these applications fail because they pass Xcms color names to XParseColor [1]. These would be color names of the form:
rgb:<red>/<green>/<blue>
rgbi:<red>/<green>/<blue>
CIEXYZ:<X>/<Y>/<Z> 
CIEuvY:<u>/<v>/<Y> 
CIExyY:<x>/<y>/<Y> 
CIELab:<L>/<a>/<b> 
CIELuv:<L>/<u>/<v> 
TekHVC:<H>/<V>/<C>
