Chasing rainbows
English Idiom
Meaning: Pursuing something that is unattainable or unrealistic. It's like going after a goal that is beautiful and appealing but ultimately impossible to achieve.
Origin: The idiom 'chasing rainbows' is believed to have originated from the folklore that a pot of gold can be found at the end of a rainbow. Since a rainbow's end is an illusion and cannot be reached, the idea of chasing it symbolizes pursuing an impossible goal.
