Meaning and history
Indigo is derived from the English word indigo, referring to the purplish-blue dye or color, which ultimately comes from Greek Ἰνδικόν (Indikon), meaning “Indic” or “from India.”
Indigo rose from #921 to #854 for girls between 2024 and 2025. That year also produced its highest recorded birth count, at 318.
