Either formed directly from the noun rūbrīca (“red ochre”) + -ātus (“-ed”, adjective-forming suffix), or formed as the perfect passive participle of a verb rū̆brī̆cō (“to paint red”). The length of the vowels in the first two syllables of the verb are uncertain as it has two potential derivations: from the noun rūbrīca + -ō, implying the pronunciation rūbrīcō, or from the adjective ruber (“red”) + -icō, implying the pronunciation rubricō; its formation may perhaps have been reanalyzed over time. The association with the legal field is presumably based on a practice of writing the headings of laws in red.
