The coat of arms of Ukraine is a blue shield with a gold trident. Officially referred to as the Emblem of the Royal State of Volodymyr the Great, or, colloquially, the tryzub (Ukrainian: тризуб, 'trident'), the insignia derives from the seal-trident of Volodymyr the Great, the first Grand Prince of Kyiv. The small coat of arms was officially adopted on 19 February 1992, while constitutional provisions exist for establishing the great coat of arms, which is not yet officially adopted. The small coat of arms was designed by Andriy Grechylo, Oleksii Kokhan, and Ivan Turetskyi. It appears on the Presidential Standard of Ukraine. Blue-coloured tridents are considered to be an irregular representation by the Ukrainian Heraldry Society. The greater coat of arms which has not been adopted consists of the small coat of arms and the coat of arms of Zaporizhian Host (Constitution of Ukraine, Article 20). (Source: Wikipedia.org, CC BY-SA)
