I'd rather stick with "dark pattern", which on its own literally means nothing (abstract notions don't have physical colors or brightness), and so can be safely assigned a specific meaning in a specific context without risk of ambiguity or even deception.
Has the nuance of a choice of color-scheme. Needs to have the nuance of being a totally dick-move that should be utterly illegal and turn your stomach.
But I guess a lot of people love those dark patterns for every silicon valley company to be using them. Probably grates to think of them for what they actually are.
