10 Flag Facts That Make Coloring More Interesting

1. No two national flags are the same. Every country’s flag is officially unique — although some come remarkably close (Romania and Chad are almost identical, and Chad’s flag only differs by a very slightly different shade of blue).
2. The most common flag color is red. Red appears on more national flags than any other color — approximately 74% of all national flags include red. Blue appears on about 53% and green on about 44%.
3. Only one country has a flag that isn’t rectangular. Nepal’s flag is the only national flag in the world with a non-rectangular shape — it consists of two stacked triangular pennants forming a double-pennant shape.
4. The American flag has been changed 27 times. A new star is added every time a new state joins the union. The current 50-star version was adopted on July 4, 1960, after Hawaii became the 50th state in 1959.
5. Nepal and Switzerland have non-standard proportions. Most flags are rectangular with a 2:3 or 1:2 ratio. Switzerland’s flag is perfectly square, and Nepal’s is the only non-quadrilateral national flag.
6. The UK flag has a deliberate asymmetry. The diagonal red stripes of the Union Jack are not centered in their white bands — they are offset toward the upper hoist on each side, representing the subordination of St Patrick’s cross to St Andrew’s cross. Getting this right when coloring the Union Jack makes it look authentic.
7. Libya briefly had the simplest flag ever. Between 1977 and 2011, Libya’s flag was a plain solid green rectangle with nothing else on it — the only single-color national flag in modern history.
8. Canada’s maple leaf is 11 pointed, not a real maple leaf. A real maple leaf has 23 lobes. Canada’s flag maple leaf was redesigned in 1964 to have 11 points specifically because the shape reads clearly at small sizes, in wind, and from a distance — it’s a graphic design object, not a botanical specimen.
9. The green on Brazil’s flag represents the rainforest. The yellow diamond represents gold, the blue circle represents the sky over Rio de Janeiro on the night of November 15, 1889 (when the republic was proclaimed), and the stars represent the Brazilian states.
10. Bhutan’s flag features a dragon. The Druk (Thunder Dragon) on Bhutan’s flag is one of the most elaborate animal illustrations on any national flag, with white scales representing purity, the four jewels in its claws representing wealth, and the two colors (orange and yellow) representing Buddhism and royal authority.
