The flag of Austria consists of three horizontal stripes: red, white and red in the appropriate sequence and has no additional symbols such as a coat of arms, which makes it very simple. The flag was officially approved in 1945, although its roots date back to the 13th century. According to legend, the red color symbolizes the blood shed in battles, and the white color symbolizes purity and peace.
The Lebanese flag consists of the same colors, only the proportions of the width of the stripes are similar to the flag of French Polynesia, namely 1:2:1, while the Austrian flag has the same stripes. The Lebanese flag also features a green cedar tree in the center, which is the country's national symbol. The flag was approved in 1943, and the red color symbolizes the blood shed for freedom, while the white stripe represents peace. In general, this interpretation of white and red colors is typical for all flags that use them, so there is nothing surprising here.

The meaning of the symbolism of the flag of French Polynesia has already been mentioned above, so there is no point in repeating it. In general, Austria, French Polynesia, and Lebanon have similar color schemes, and not only them, there are actually more flags, for example, the flag of Latvia, but these three are the most similar and appropriate for comparison, but do not forget that they are only outwardly similar and each of them has its own history and meaning for its people.
