The flag of Trinidad and Tobago was adopted upon independence from the United Kingdom on 31 August 1962. Designed by Carlisle Chang (1921–2001), the flag of Trinidad and Tobago was chosen by the independence committee of 1962. Red, black and white symbolise fire (the sun, representing courage), earth (representing dedication) and water (representing purity and equality).
The flag of Trinidad and Tobago is a red field with a white-edged black diagonal band from the upper hoist-side to the lower fly-side. In blazon, Gules, a bend Sable fimbriated Argent.
The width of the white stripes is 1⁄30 of the flag length and the width of the black stripe is 2⁄15. The total width of the three stripes together is therefore 1⁄5 of the length.
The civil ensign is the national flag in a 1:2 ratio. The naval ensign (used by coast guard vessels) is a British white ensign with the national flag in the canton.
