Cienna is an American spelling of Sienna, the name of the Tuscan city of Siena and of the warm reddish-brown earth pigment made famous by its painters, so it can be read as "reddish brown" or simply "from Siena". The C spelling nods to Ciara and Cienna sounds exactly like its model. Cienna peaked at number 1241 in the United States in 2006 and ranks at number 1598 in 2025.
