The notable difference in the popular system is the widespread use of the term "moreno". This is difficult to translate into English, and carries a few different meanings. Derived from Latin "maurus", meaning inhabitant of Mauritania, it has traditionally been used to distinguish White people with dark hair, as opposed to "ruivo" ("redhead") and "loiro" ("blonde"). It is also commonly used as a term for people with an olive complexion, a characteristic that is often found in connection with dark hair. In this connection, it is applied as a term for suntanned people, and is commonly opposed to "pálido" ("pale") and "amarelo" ("yellow"), which in this case refer to people who are not frequently exposed to sun. Finally, it is also often used as a euphemism for "pardo" and "preto".
