Have the client which creates the property open another server connection for
this, allocate the colors, create a 1x1 pixmap, set the close down mode to
RetainPermanent and put the XID of the pixmap along with the other infomation
inside that property on the root window.

To get rid of the shared colors, you'll just need to do a KillClient on the
pixmap ID (which is what it's for).  Check out how the various root-window
setting applications register the root pixel value inside a property along with
a pixmap.
