State symbols of many statesare sustained in this color scheme. The American star-striped "Stars and Stripes" is often referred to in songs and verses as "Red White and Blue" (red, white, blue). The flag of the Russian Federation is also sustained in these tones, which caused a lot of imitations among the newly formed Slavic states in the nineteenth century (Serbia, Slovakia, Slovenia).
Different-different, blue-white-red
These colors are common in the heraldry ofother continents. The state symbols of Thailand and Costa Rica are so similar that it is not so easy to discern where the flag is. Red, white, blue middle (twice as wide), then again white and red strip - in Thailand. Costa Rican colors are opposite, except for white.
But really in such a sequence, from top to bottom, colors are located only on the banners of the three countries. These are Luxembourg, the Netherlands and Croatia.

Croatian tricolor with the coat of arms
The constitution of each country indicates the proportionsone of the most important state symbols. The Croatian tricolor consists of three colors (red, white, blue). The flag is twice as long as the width. In the center is the coat of arms, and it is not easy. Not only that the shield is divided into red cells (there are 25 of them), it is crowned by the royal crown, consisting of five segments representing the icons of Slavonia, Dalmatia, the Republic of Dubrovnik, Istria and Croatia itself. The coat of arms is very ancient, it has been known for almost a thousand years, and each of its elements is filled with deep meaning. The year 1848 was the date when Josip Jelacic took over Bana's duties, dressing the outfit in which these three colors were combined: red, white, blue. The flag from that moment symbolizes the national unity. Thanks to the coat of arms, a rather complex figure, it is easy to distinguish the Croatian team in any sports competitions.

Dutch Royal Flag
Very similar to the Croatian symbol of the Netherlandsflag, white-red-blue. The country found it much later, in 1648, when on the traditional standard of the Prince of Orange, the upper orange band gave way to the red revolutionary field. Then, in 1815, the Netherlands became a kingdom, but nothing changed. It is interesting that there is a version explaining the reason for this color scheme. Practical Dutch seafarers noticed that the orange matter quickly sheds on the flagpoles, unlike the red one. But during the festive holidays, celebrated with royal splendor, they recall both the old monarchical symbol and, along with the state attributes, hang it, with the orange top band.

Luxembourg and the flag related to the Netherlands
In the common gamut one moreEuropean flag - red, white, blue. Horizontally arranged colors de facto symbolize since 1815 the Grand Duchy of Luxembourg. True, it was officially approved relatively recently, in 1972. The proportions of the sides are also original, they can vary - either three to five, or one to two.
The similarity of the flags of the two neighboring countries is explained bythe fact that the Dutch king Willem I, who ascended the throne in 1815, combined two posts, he was also the Luxembourgish duke. It was he who introduced this flag, with one caveat: the lower blue band became lighter. History is silent about whether this is due to burn-out in the sun.
Similarity does not give rest to someparliamentarians. CHPP (Christian Social People's Party), through the words of its leader Michel Voltaire, suggested replacing the former unity with the Netherlands, and therefore, perhaps, irritating colors: red, white, and blue. The "Red Lion" flag, proposed as a new state symbol, is already used in civil courts and has a long history associated with the royal dynasty. It is possible that a constitutional amendment will be adopted, and Luxembourgers can be congratulated with a new flag. Moreover, the idea is supported by the majority of the population.
