Latvians have a tradition of dyeing eggs for Easter using onion skins, which produces various colors depending on how long the eggs are immersed. Eggs can be decorated by attaching leaves or flowers before dyeing, leaving a lighter pattern. Another method is to boil the dyed egg and scratch a pattern into it. The eggs are often dyed the day before Easter and used in an egg-knocking game on Easter morning, with the owner of the intact egg said to live longest.
