What do the colors of the Oman flag mean?

The red base is taken from Oman's previous flag and represents the reigning Al Bu Said dynasty, which has been ruling Oman since the mid-18th century and also symbolizes the difficulties Oman overcame in its search for independence. The color white historically represents the imam, the Islamic religious leaders of the country and also stands for peace and prosperity. Green is the color of Islam and represents the fertility of the country as well as Al Jabal al Akhdar (the Green Mountains) in the north-east of the country.
