The flag most commonly described as “red, yellow and green” is the national flag of Ethiopia.

Quick Scoop

Several national flags use the red–yellow–green combination, but Ethiopia is the classic and historically important one people usually mean.

  • Ethiopia: Horizontal stripes of green, yellow, and red with a blue disc and yellow star in the center on the modern flag.
  • These three colors became known as “Pan‑African colors” and inspired many other African countries’ flags, like Ghana, Guinea, Senegal, Mali, and Benin, which all use red, yellow, and green in various layouts.

What those colors usually mean

In many of these flags, the colors carry similar symbolic ideas:

  • Red – blood, sacrifice, struggle for independence, or courage.
  • Yellow/Gold – wealth, the sun, energy, or mineral resources.
  • Green – land, nature, agriculture, fertility, or hope.

So if you saw a simple tricolor flag that’s red, yellow, and green and someone asks “what flag is red yellow and green?”, they’re most often talking about Ethiopia or one of the Pan‑African‑inspired national flags from Africa.
