Which country flag is blue and yellow?

Ukraine

• The flag of Ukraine consists of two equal horizontal bands: blue on top and yellow on the bottom. The blue represents the sky, and the yellow symbolizes wheat fields (U.S. Embassy in Georgia).
• Ukraine’s parliament adopted the current flag in 1992, though it was used earlier during the 1917–1921 independence period (U.S. Embassy in Georgia).

Sweden

• Sweden’s flag is a blue field with a yellow Scandinavian cross that extends to the edges. The design dates back to the 16th century and was officially adopted in 1906 (Wikipedia).
• The colors are said to derive from the Swedish coat of arms, where blue represents loyalty and yellow stands for generosity (Wikipedia).

Kazakhstan

• Kazakhstan’s flag is a blue field with a yellow sun and a soaring eagle in the center, and a vertical yellow ornamental band near the hoist. The blue represents the sky and water, the sun and eagle symbolize freedom and strength (Wikipedia).
• Adopted on June 4, 1992, shortly after independence (Wikipedia).

Palau

• Palau’s flag is a light blue field with a yellow circle slightly off-center toward the hoist. The blue represents the ocean, the yellow circle symbolizes the moon (Wikipedia).
• Adopted on January 1, 1981, when the country became self-governing (Wikipedia).

The pattern: All four countries use blue and yellow as their sole colors, but each interprets the palette differently—sky, sea, sun, agriculture, and freedom all appear through the same two hues.

Which places have a blue and yellow flag?

National flags

• Beyond the four exclusive blue-and-yellow flags, several national flags include blue and yellow alongside other colors. For example, the flag of Barbados has vertical blue, gold, and blue stripes with a black trident head (Britannica).
• The flag of the European Union is a blue field with twelve yellow stars in a circle, representing unity and harmony (Wikipedia).
• Kosovo’s flag is blue with a yellow map of the country and six white stars above it (Wikipedia).

Regional flags

• Several Irish counties use blue and yellow flags. For example, County Longford’s flag is blue with a yellow lion, County Tipperary uses blue and yellow horizontal stripes, and County Wicklow flies a blue flag with a yellow saltire (Wikipedia – List of flags of Ireland).
• The flag of the Irish Traveller Movement is blue with a yellow sunburst design (Wikipedia).

Organizational flags

• The European Union flag, as mentioned, is one of the most recognizable organizational flags with blue and yellow. Other organizations, such as the United Nations (blue and white) and NATO (dark blue), use blue but not yellow.

The implication: Blue and yellow flags extend far beyond national borders—they serve as regional identifiers and organizational symbols, especially in Europe.

What flag is 🇪🇨?

Ecuador flag description

• The emoji 🇪🇨 represents the national flag of Ecuador. The flag consists of three horizontal stripes: yellow (top half), blue, and red, with the national coat of arms centered in the yellow stripe (Wikipedia).
• Ecuador is located in South America, bordered by Colombia, Peru, and the Pacific Ocean.

The catch: Ecuador’s flag is often confused with Colombia’s because both use yellow, blue, and red, but Ecuador has a coat of arms.

What flag is 🇮🇪?

Ireland flag description

• The emoji 🇮🇪 stands for the flag of Ireland, which is a vertical tricolor of green, white, and orange. The green represents Catholics, orange represents Protestants, and white symbolizes peace between them (Wikipedia).
• There is also the flag of Northern Ireland (the Union Jack variant) and the St. Patrick’s Saltire (a red saltire on a white field), which is sometimes referred to as the flag of Ireland in historical contexts but is not the national flag.

Are there two Irish flags?

• Yes, there are multiple flags associated with Ireland. The national flag is the green-white-orange tricolor. However, the blue and yellow flag of Ireland is not the national flag; it represents Irish counties like Longford, Tipperary, and Wicklow, as well as the Irish Traveller Movement (Wikipedia).

Why this matters: The blue and yellow flag of Ireland is a common search term, but it refers to regional identity, not the country itself.

What flag is 🇻🇨?

Saint Vincent and the Grenadines flag description

• The emoji 🇻🇨 represents the flag of Saint Vincent and the Grenadines. The flag has three vertical stripes: blue, yellow, and green, with three green diamonds in the center of the yellow stripe (Wikipedia).
• The blue represents the sky and sea, the yellow stands for the sunshine, and the green symbolizes the lush vegetation. The diamonds represent the islands of Saint Vincent and the Grenadines.

The pattern: This flag uses blue and yellow as part of a broader palette, typical of Caribbean flags.

What flag is 🇪🇭?

Western Sahara flag description

• The emoji 🇪🇭 represents the flag of Western Sahara (Sahrawi Arab Democratic Republic). The flag consists of black, white, and green horizontal stripes with a red triangle at the hoist, and a red crescent and star in the center (Wikipedia).
• This flag does not contain blue or yellow. It is included here because users sometimes search for it among blue and yellow flags due to emoji confusion.

What flag is 🇨🇴?

Colombia flag description

• The emoji 🇨🇴 represents the flag of Colombia. It has three horizontal stripes: yellow (top half), blue, and red. The yellow represents gold, blue the seas, and red the blood of patriots (Wikipedia).
• Colombia’s flag is nearly identical to Ecuador’s but without the coat of arms.

The pattern: Colombia and Ecuador share the same color scheme, making them easy to confuse—especially in emoji form.
