Etymology: The word is a blend of two older colour-coded images. In Western fiction, heroes wore white hats and villains wore black ones, and the same contrast ran through chivalric romance, where white knights stood against black knights. Security hackers borrowed that black-and-white code: "black hat" came to mean a malicious intruder and "white hat" a hacker who works for the defence. Someone who falls between the two, bending rules without being plainly criminal, sits in the grey zone between them. The colour itself carries the moral idea. Grey is a mix of black and white, so it naturally stands for ambiguity, a character neither wholly good nor wholly bad. The expression works as a compound of "gray" and "hat," with "hat" standing in for the whole costume-based system of moral signalling that the earlier heroes and villains established.
