Red
In Hebrew, the name refers to the color red, specifically the reddish soil of the region south of the Dead Sea. Historically, it is the name given to Esau in the Bible after he sold his birthright for red lentil stew. While traditionally masculine in a biblical context, it is occasionally used as a rare, gender-neutral choice in modern times.
