Morphology

gray + hat

The adjective 'gray' clearly conveys an intermediate or indeterminate position, which partly signals the idea of being between ethical and unethical. However, 'hat' is used metaphorically here as a technical/jargon label for a role (as in 'white hat'/'black hat' hackers), a usage that B1 learners who only know the literal sense 'hat' may not recognize. Because the composition gives a useful hint but relies on domain-specific metaphorical usage that is not fully predictable to learners, the MWE is only partially transparent.

Etymology

Gray hat comes from hacker slang that called helpful hackers 'white hats' and bad ones 'black hats'. Because gray is between white and black, a gray hat works between 'good' and 'bad', sometimes helping and sometimes breaking rules.
