Green White Blue Flag: +3 Country Flags

October 30, 2026

There are only three countries that use the color green, blue and white on their flags.

However, many cities used these colors in their flags. I divided the blog post into three equal parts. Countries in the first part, cities and states in the second part.

And in the last part, there are historical flags, including flags of former organizations.

Country Flags

Lesotho

Lesotho flag

The flag has blue, white and green bands, with a black Basotho hat in the middle. The hat is called a mokorotlo.

Lesotho became independent in 1966; the current flag followed in 2006.

If you are considering visiting this place, I suggest you start from Maseru, the capital.

Uzbekistan

Uzbekistan flag

The flag of Uzbekistan was adopted on 18 November 1991, after independence from the Soviet Union. Thin red lines separate the blue, white and green bands; the upper corner holds a crescent and twelve stars.

You can see centuries of history in cities like Samarkand. Plov is another familiar part of Uzbek culture: a rice dish made with meat, onions and carrots.

Sierra Leone

Sierra Leone flag

Sierra Leone has my favorite colors among these national flags. Green at the top, white in the middle and blue at the bottom: no emblem interrupts the three bands.

City & Regional Flags

The same colors also appear in town, county and regional flags.

Blachownia

Blachownia Flag

Blachownia is a town in southern Poland. Its flag reminds me of the Cuban flag because of the triangle at the hoist, though the rest of the design differs: a green triangle meets just two horizontal bands, white above blue.

San Pedro Department

San Pedro Department flag

This is San Pedro Department in Paraguay. The pictured flag has vertical blue, white and green bands, with the departmental seal in the white band.

Khabarovsk Krai

Khabarovsk Krai flag

Light blue and green meet white in the Khabarovsk Krai flag. The green triangle stretches in from the hoist, while white and blue divide the rest horizontally.

The region is in the Russian Far East. If you plan a winter visit, checking the weather twice is still good advice.

Guaviare

Guaviare flag

The dark green and blue in the flag of Guaviare sit on either side of a white band. Guaviare is a department of Colombia.

Gloucestershire

Gloucestershire flag

The Gloucestershire flag is my favorite of the cross flags. The blue cross has a cream border against green, so its light detail is cream rather than pure white.

Gloucestershire is an English county, and Gloucester Cathedral is one of its historic landmarks.

Los Lagos

Los Lagos flag

Four white stars sit in the upper green half of the Los Lagos regional flag from Chile. Blue fills the lower half.
