IIUC, neither Carbon nor Cocoa defines the standard textual
representation formats of colors.  So I think Emacs on such platforms
should adopt some other standards (e.g., X11 or maybe CSS) like in the
W32 or Carbon port rather than inventing new own formats as in the NS
port.  Own formats does not enhance interchangeability in any ways.
