Etymologically, the entry records: Borrowed from French rouille (“rouille (sauce); rust”); the sauce is so named because its colour resembles that of rust. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear.
