Have you ever wondered why so many people pick the same two colors for their home? Blue and white feel right together. They remind us of the ocean hitting the shore or a bright sky on a clear afternoon. It makes sense that countries with blue and white flags chose this look to show off their own pride and calm spirit.
These flags often represent big ideas, such as freedom or the deep sea that sustains a nation. From the islands of Greece to the snowy hills of Finland, each design carries a different vibe. These 12 countries with blue and white flags tell you how a simple pair of colors can tell a thousand different stories.
Why Did These 12 Countries with Blue and White Flags Choose These Colors?
There are 12 countries with the colors blue and white in their flags. Here is the name of the countries whose flags are colored in blue and white:
1. Finland
- Adopted: May 29, 1918
- Designers: Eero Snellman, Bruno Tuukkanen
- Symbolism: Blue cross – Nordic Heritage, white field – snow
Finland adopted the Siniristilippu, or “Blue Cross Flag,” in 1918 after gaining independence from Russia. The design uses the Nordic Cross to signal its cultural ties to Sweden and Denmark. Its white field represents the thick snow of Finnish winters, while the blue cross mimics the color of the nation’s 188,000 lakes. This flag avoids complex crests, focusing instead on a clean aesthetic that mirrors the country’s famous love for functional, simple design.
2. Guatemala
- Adopted: November 26, 1871
- Designer: Miguel Tejada
- Symbolism: Blue – sky/coast, white – peace/purity
Guatemala uses vertical stripes to distinguish itself from its neighbors. The two sky-blue bars represent the country’s position between the Pacific and Atlantic Oceans. In the center, a white stripe holds the national emblem, featuring the Resplendent Quetzal bird, which symbolizes freedom. Among countries with blue and white flags, Guatemala stands out because its specific shade of blue, known as “Celeste,” seems to reflect the actual brightness of the Guatemalan sky.
3. Honduras
- Adopted: February 28, 1866
- Designer: Augusto C. Ferrer
- Symbolism: Blue – Pacific/Atlantic/Caribbean, white – peace, stars – unity
The Honduran flag features three horizontal stripes and five blue stars. These stars are the most critical element; they represent the five nations of the former Central American Federation. By keeping these stars in the center, Honduras signals its enduring hope for a unified Central American state. The blue stripes represent the Caribbean Sea and the Pacific Ocean, while the white band signifies the goal of peace and the purity of the citizens’ thoughts.
4. Argentina
- Adopted: February 25, 1816 (sun 1818)
- Designer: Manuel Belgrano
- Symbolism: Light blue – Río de la Plata/justice, white – peace, sun – independence
Argentina’s Albiceleste features two light blue bands and a central white band. Manuel Belgrano created the design during the War of Independence, reportedly inspired by the colors of the Argentine sky or the cockades used by revolutionaries. The “Sun of May” in the center is a replica of the engraving on the first Argentine coin. It features sixteen straight and sixteen wavy rays, representing the Incan sun god, Inti, and the dawn of a new nation.
5. El Salvador
- Adopted: May 27, 1912
- Designer: Antonio Regalado
- Symbolism: Blue – Pacific/sky, white – peace, coat of arms – nature/unity
El Salvador uses a bold cobalt blue for its two outer horizontal stripes. These represent the sky and the vast waters of Central America. The white stripe contains the national coat of arms, which is dense with meaning: it features five volcanoes for the five original Central American provinces and a rainbow for hope. Unlike more minimalist designs, this flag uses its central space to tell a detailed story of volcanic geography and revolutionary triumph.
6. Nicaragua
- Adopted: September 4, 1908
- Designer: Edouard Walther
- Symbolism: Blue – Pacific/Lake Nicaragua, white – peace, coat of arms – federation
Nicaragua’s flag closely mirrors the old United Provinces of Central America design. The two blue stripes symbolize the Pacific Ocean and the Caribbean Sea that border the nation. Inside the white stripe sits a coat of arms featuring a triangle, which represents equality. Inside that triangle, five volcanoes rise under a “Cap of Liberty” and a rainbow. It emphasizes a message of balance and highlights the country’s unique landscape as the land of lakes and volcanoes.
7. Micronesia
- Adopted: November 30, 1979
- Designer: Dudley Carter
- Symbolism: Blue – Pacific Ocean, 4 stars – islands
The flag of Micronesia features a light blue field with four white stars arranged in a diamond. The blue represents the Pacific Ocean, while the stars signify the four island groups: Chuuk, Pohnpei, Kosrae, and Yap. Originally, the flag had six stars, but the design changed as territories shifted. By using a simple layout, the nation emphasizes unity across a vast maritime territory. It stands as a clear example of how countries with blue and white flags use celestial symbols to map out their physical geography.
8. Greece
- Adopted: December 22, 1978 (design 1822)
- Designer: Unknown
- Symbolism: Blue/white stripes – 9 syllables anthem, cross – faith
The Greek flag, often called the “Galanolefki,” consists of nine horizontal stripes of blue and white. These stripes represent the nine syllables of the phrase “Eleftheria i Thanatos,” which means “Freedom or Death.” The blue signifies the Mediterranean Sea and the sky, while the white symbolizes the purity of the struggle for independence. A white cross sits in the top left corner, representing Eastern Orthodox Christianity, the established religion of the nation.
9. Somalia
- Adopted: October 12, 1954
- Designer: Mohammed Osman
- Symbolism: Blue – sea/peacekeeping, white star – unity/Muhammad’s faith
Somalia’s flag is strikingly minimalist, featuring a single white five-pointed star centered on a light blue field. The shade of blue was originally inspired by the United Nations flag to thank the organization for its help during the country’s transition to independence. The star is known as the Star of Unity. Each of its five points represents a region where the Somali people traditionally lived, including areas in Ethiopia, Djibouti, and Kenya.

10. Israel
- Adopted: October 28, 1948
- Designer: League of Zionists
- Symbolism: Blue stripes – tallit/prayer shawl, Star of David – Judaism
The Israeli flag features two horizontal blue stripes on a white background with a blue Star of David in the center. The design is modeled after the Tallit, a Jewish prayer shawl. This choice connects the modern state directly to ancient religious tradition. The blue stripes represent the stripes on the shawl, and the Star of David (Magen David) has been a symbol of Jewish identity for centuries. It is a rare instance where a national flag’s layout is derived entirely from a specific garment.
11. Uruguay
- Adopted: July 11, 1830
- Designer: Joaquín Suárez
- Symbolism: Blue/white – sky/Los Andes/peace, sun – independence
Uruguay’s flag consists of nine horizontal stripes: four blue and five white. These stripes represent the nine original departments of the country. In the top left corner, the “Sun of May” features a human face with sixteen rays, alternating between straight and wavy. Like Argentina, Uruguay uses this sun symbol to honor the 1810 revolution and the Incan sun god. The design balances a European-style stripe pattern with indigenous and revolutionary icons.
12. San Marino
- Adopted: 1468 (current 2011)
- Designer: Traditional
- Symbolism: White – peace/Guardi Mountain, blue – sky/Freedom Tower
San Marino, one of the world’s oldest republics, uses two horizontal bands of white and light blue. The white represents the clouds and the snow on Mount Titano, while the blue symbolizes the sky. The national coat of arms sits in the center, featuring three towers, Guaita, Cesta, and Montale, which represent the three peaks of the mountain. A crown sits on top to symbolize sovereignty, and the word Libertas (Liberty) appears at the bottom.
White and Blue: Why do They Appear in So Many Flags?
Did you know Purple was the rarest color ever used in a flag? In all of the 196 countries, almost none have purple. But do you know what the most common color is? Red, blue, and white.
According to the Guinness Book, White and Blue appear in 71% and 50% of all national flags, respectively. Now you may wonder who?
Let’s try to understand it together, shall we?
Now, there is a historical reason behind the use, then there is symbolical reason and a practical reason.
We have already gone through the history and symbolism of the countries with blue and white flags; let’s talk about the practical reason. And the reason is simple: These hues dye durably, white via bleaching, blue with stable pigments, and ensure flags remain visible from afar without fading. High contrast aids recognition in battles or at sea.
See, in the Middle Ages, white was achieved through simple bleaching of linen or cotton, making it cheap and fade-resistant for long-term use. Blue came from woad (a plant-based dye) or, later, indigo, which were stable and widely available in Europe via trade routes, unlike vibrant reds or yellows that faded quickly in sunlight.
And that is why we see so many blue and white in the flags.
Conclusion
Each flag acts as a vivid map of a nation’s soul, proving that color is never just a decorative choice. These designs turn fabric into a testament of survival and hope. Exploring countries with blue and white flags reveals a shared human desire to capture the essence of the earth and sky.
These stories show that a simple palette can hold the weight of entire revolutions and ancient traditions. While they share a color scheme, these countries with blue and white flags fly with a distinct rhythm and purpose. It is a reminder that even when we use the same colors, the identities we build remain beautifully diverse.
