This quiz features 13 national flags, all designed with shades of blue and white. While they share a similar color palette, the flags vary greatly in style, symbolism, and history.

Some are instantly recognizable, like the Star of David on Israel’s flag or the blue cross of Finland. Others might be more of a challenge—can you spot the difference between the flags of Honduras, El Salvador, and Nicaragua? And what about Botswana’s pale blue design with a bold black stripe, or the unique five stars of Micronesia?

From Greece to Guatemala, these flags demonstrate how a limited set of colors can be used in creative and distinctive ways. See how many you can identify correctly!
