Are United States diplomatic passports Green?

United States passports are issued to citizens and nationals of the United States of America for the purpose of international travel. They entitle the bearer to the protection of US consular officials overseas. Responsibility for their issuance lies with the Passport Services of the Bureau of Consular Affairs within the Department of State, which has numerous acceptance agencies and agents. For citizens abroad, passport applications are forwarded back to a passport center by the local US embassy or consulate.
