Similar to The Curse of Number Two, the Curse of Green is another "curse" in the Eurovision Song Contest that involves the colour green being used on stage or worn by the performer.
Usually, but not in all situations, the performer fails to do well, doesn't qualify to the final or is the victim of the Barbara Dex Award of that year.
The Eurovision Song Contest 1968 was the first to be broadcast in colour, so any participants before that year are unknown to have worn green on the night of their performance or have green on the stage.
Katja Ebstein of Germany in 1970 is the first recorded person to have the Curse of Green, whereas Alvan & Ahez of France are the most recent. They finished second last in the 2022 contest while including green lights in their performance.
A notable aversion would be Käärijä in 2023, who came second and won the public vote despite wearing a green bolero and including green lights in his staging.
