The Unicode Technical Committee (UTC) is discussing a mechanism for color
changes to existing emoji characters. Such a mechanism could be used for
emoji representations of a black cat or a glass of white wine, for example.
The color mechanism would use the emoji color characters (including the
seven colored square characters at U+1F7E6..U+1F7EB) that were added to the
Unicode Standard Version 12.0 in early 2019.
Emoji color mechanisms could potentially be defined as part of
Unicode Emoji 13.0. The topic will be discussed at the upcoming July UTC
meeting. Specific proposals for new colored emoji characters will not be
taken up until the fundamental color mechanism has been established.

Draft for Proposed Update UTS #51: Unicode Emoji, section 2.9 “Color”.
The Unicode Standard is the foundation for all modern software and
communications around the world, including operating systems, browsers,
laptops, and smart phones—plus the Internet and Web (URLs, HTML, XML, CSS,
JSON, etc.). The Unicode Standard and its associated standards and data form
the foundation for CLDR and ICU releases.
