Which countries have green, yellow and blue flags?
- Brazil (South America): a green field with a large yellow diamond and a blue globe. It is the only one of the five with a large yellow diamond.
- Gabon (Africa): three horizontal stripes of green, yellow and blue.
- Solomon Islands (Oceania): a diagonal split, blue above and green below, with a yellow stripe and five white stars.
- St. Vincent & Grenadines (North America): vertical blue, yellow and green bands with three green diamonds in a V shape.
- Christmas Island: a blue and green diagonal flag with a golden disc showing a green map of the island, a golden bosun bird and the Southern Cross.
To tell them apart, check the layout first. Horizontal stripes mean Gabon. Vertical bands mean St. Vincent & Grenadines. A diagonal means Solomon Islands or Christmas Island, and a yellow diamond means Brazil.
Flags that include these colors with others are Central African Republic, Eritrea, Ethiopia, Comoros, Mauritius, New Caledonia, Seychelles and South Africa.
Why are green, yellow and blue used on flags?
These three colors often point to land, sunshine and water. Green stands for forests and farmland, yellow for sun, sand or mineral wealth, and blue for the sea or sky.
Brazil's colors come from the old imperial flag, where green stood for the House of Braganza and yellow for the House of Habsburg. Popular tradition reads them as forests and gold, with the blue globe showing the sky over Rio de Janeiro on the day the republic was proclaimed. The Caribbean and Pacific flags use it too. In St. Vincent & Grenadines the blue stands for sky and sea, yellow for sunshine and green for vegetation. The Solomon Islands use blue for the ocean, green for the land and yellow for the sun.
Gabon's flag follows a similar logic: green for the forests that cover most of the country, yellow for the equator that crosses it and blue for the Atlantic coast. Christmas Island, an Australian territory in the Indian Ocean, uses green for land and blue for sea, with the Southern Cross added.
Frequently asked questions
What flag is green, yellow and blue?
Brazil, Gabon, Solomon Islands, St. Vincent & Grenadines and Christmas Island are built from these three colors, apart from small white details.
What is the green flag with yellow and blue?
Brazil has a green field with a yellow diamond and a blue globe. Gabon and St. Vincent & Grenadines are striped instead.
What flag has horizontal green, yellow and blue stripes?
Gabon. Its stripes run green, yellow, blue from top to bottom.
How many flags use green, yellow and blue?
Five flags are built from only these colors, and thirteen include all three.
Which flags with blue, green and yellow also have red?
Eritrea, Ethiopia, Mauritius and New Caledonia add red to the three colors and use nothing else. The Central African Republic, Comoros and Seychelles add red and white, while South Africa uses six colors in all. All of these are among the thirteen flags that contain blue, green and yellow.
Which blue, green and yellow flag has a diagonal stripe?
The Solomon Islands. A yellow diagonal stripe divides a blue upper triangle from a green lower one, and five white stars sit in the corner by the hoist. The white stars are small, so the flag still counts as blue, green and yellow.
Which flag has three green diamonds on a yellow band?
St. Vincent & Grenadines. Its flag has blue, gold and green vertical bands, with three green diamonds in the middle arranged in the shape of a V, a subtle nod to the first letter of Vincent. The yellow band sits between the blue and green ones, so the flag reads blue, gold, green from left to right.
