It is part of a thread from 2002 about the possibility of chromatic fonts. I wonder if it would be possible please for Unicode to have a Chromatic property that works exactly like the emoji property in the sense of expressing that a colour version of the glyph is being requested so that characters such as the one to which Daniel refers in his post linked above can be listed in The Unicode Standard as having a variation selector for a Chromatic version as that would be a respectful terminology for characters used in such applications. I also found this post of mine. http://unicode.org/mail-arch/unicode-ml/y2002-m06/0403.html Something to think about? William Overington Thursday 6 April 2017
