On February 22, 1979, Saint Lucia became an independent state of the Commonwealth of Nations associated with the United Kingdom. The island nation celebrates this every year with a public holiday. St. Lucia is also a member of la Francophonie.
The flag has four distinctive colours. The [Cerulean] Blue represent fidelity. It reflects our tropical sky, and also our emerald surrounding waters, the Caribbean Sea and the Atlantic Ocean. The Gold represents the prevailing sunshine in the Caribbean, and prosperity. The Black and white reflects the cultural influences. The white part, white culture; the black, black culture – the two races living and working in unity.
The flag was designed by Dr The Honourable Dunstan Gerbert Raphael St. Omer, renowned St. Lucian artist, who was knighted in the 2009/2010 New Year's honours list, for his services to art. The investiture ceremony was held on 9 April 2010, at Government House where the Governor General on the advice of Her Majesty the Queen, invested Sir Dunstan St. Omer with the Insignia of a Knight Commander of the Order of St Michael and St George (KCMG). The UK Telegraph has described him as “the Michelangelo of the Caribbean.
The design impresses the dominance of Negro culture associated with that of Europe, against a background of sunshine and ever-blue sea; this is represented by the three triangles in the centre of the flag, symbolising three pitons. The triangle, the shape of which is an isosceles (triangle) coupled with the island's famous twin Pitons at Soufrière, rising sheer out of the sea—towards the sky, themselves a symbol of hope, aspirations of the people.
