Feature Request: .display can take in a font color and emoji to replace the tag

I'd be happy to put the pull request together, but I want to make sure this library is still being supported and we can get a release out without waiting for 3.x.

The issue does not name any files, tests, or entry points. Start by locating the `.display` implementation and its tests, then verify whether the library is still supported and how releases are handled. Done means `.display` accepts a font color and emoji that replace the tag, with coverage for the new behavior.
