How can you automatically highlight messages that are flagged with additional background coloring?

  • The mail app has a tiny flag in the top right of the message, but it doesn’t really draw attention.

  • This thread https://discussions.apple.com/thread/252536582?answerId=254778777022#254778777022 states that a rule can be used, but I don’t see an option to choose “flagged” messages. This used to be native behaviour in previous versions of Mac mail (don’t recall the version).

  • Do not want to go into format/colors each time as this would require flagging and manually coloring as I still was to use the flag filters.

Technical Details:

  • macOS Monterey v12.5
  • Mac Mail v16.0
