I feel there must be a word I can use to mean the opposite of "golden", but I can't think of one. For example:
golden handshake: being sacked but with excellent remuneration.
****** handshake: being sacked unpleasantly
golden ticket: winning the prised invitation
****** ticket: letter inviting you back after routine cancer screening
golden sample: an example of a product that passes the quality tests
****** sample: an example of a product that fails the quality tests
