While "moro" can be used to describe someone's skin color, it's important to remember that using it to describe a person can be offensive and is considered outdated and discriminatory.
If you need to describe someone's skin color in Italian, it's best to use more neutral terms like:
* scuro (dark)
* abbronzato (tanned)
* di carnagione scura (with a dark complexion)
* di pelle scura (with dark skin)
Remember that words can have different meanings and connotations in different languages and contexts.
