Chasing rainbows
Meaning
To pursue something beautiful, desirable, or idealistic that is ultimately unattainable or impractical.
Origin
Rainbows have captivated humanity since ancient times, appearing as shimmering arcs of light that promise wonder, often associated with mythical pots of gold at their elusive ends. This radiant, ephemeral phenomenon, however, can never actually be reached. As one moves towards it, the rainbow moves away, remaining forever at the same optical distance. This fundamental, beautiful impossibility—the pursuit of something visually present yet physically unattainable—is what gives "chasing rainbows" its poignant meaning, encapsulating the universal human experience of desiring the unreachable.
Examples
