The national flag of Estonia is a tricolor featuring three equal horizontal bands of blue (top), black, and white. The normal size is 105 x 165 cm. In Estonian, it is colloquially called the "sinimustvalge" (literally "blue-black-white"), after the colors of the bands.
There are a number of interpretations attributed to the colors of the flag. A historical interpretation of the colors has blue representing ancient freedom, black symbolizing lost independence and white, the promise of a brighter future. Another interpretation made popular by the poetry of Martin Lipp is as follows:
* blue: vaulted blue sky above the native land;
* black: attachment to the soil of the homeland as well as the fate of Estonians – for centuries black with worries;
* white: hard work, purity, commitment, and (most likely) white sails of ships.
