It depends what you mean by that... Many beaches have black sand and many have white... Hope this helps. Sorry if it doesn't. Also, you can have sandy beaches and stone/pebble beaches. Nude beaches and non-nude beaches.
Nudity is not allowed on ordinary public beaches but complete nude beaches advertise so people know it's naked people there. Of course people can be dressed there as well.
