This design is the "Nordic cross," which originated from the Danish flag and is also used by other Nordic countries. There's also a legend that Sweden's blue and yellow came from a 12th-century king who saw a golden cross in the blue sky.

This emoji also symbolizes modern Swedish culture. It's often used when talking about global brands like IKEA or Spotify, the coffee culture known as "fika," or its image as a welfare state. Try using it when you want to express a minimal and stylish Nordic vibe.
