Learn flags by colour
Colour is the fastest shortcut to identifying a flag. Each palette has meaning — pick one to see every flag that uses it.
Red
Courage, revolution, and blood shed for independence. The most common colour on Earth's flags.
Blue
Sky, sea, freedom and vigilance. Dominates Pacific and Central American flags.
Green
Land, agriculture, hope — and in many flags, Islam. Big across Africa and the Middle East.
Yellow
Sun, wealth and mineral riches. Central to Pan-African tricolours.
White
Peace, purity and honesty. The quiet workhorse of flag design.
Black
Heritage, determination, and defeat of enemies. Key to Pan-Arab palettes.
Orange
Saffron in South Asia; the House of Orange in the Netherlands and Ireland.
