Well I have an idea what Blaubeermund means:
There exists an German poen, named "Erdbeermund" (which means Strawberry Mouth in English). Erdbeermund is a paraphrase for a womans lips, but not the ones in her face, if you understand ^^.
I think Blaubeermund means the same, but for a dead person, because the lips of dead people turn blue.
Also this would fit the interpretation, of a necrophilic who works in a mortuary and who "loves" a dead woman there.
