الأوس والخزرج
The literal translation of Alhambra, "the red (feminine)", reflects the colour of the red clay of the surroundings of which the fort is made. The buildings of the Alhambra were originally whitewashed; however, the buildings as seen today are reddish. Another possible origin of the name is the tribal designation of the Nasrid Dynasty, known as the Banu al-Ahmar "Arabic: Sons of the Red (masculine)", a sub-tribe of the Arab Qahtanite Banu Khazraj tribe. One of the early Nasrid ancestors was nicknamed "Yusuf Al Ahmar" (Yusuf the Red) and hence the (Nasrid) fraction of the Banu Khazraj took up the name of Banu al-Ahmar.
