Seeing a rainbow is often considered to be lucky or a positive omen by many people. Rainbows have deep cultural and symbolic meanings in mythology, religion, and popular belief. This article will explore some of the history and folklore around rainbows being lucky, and look at some scientific explanations for how rainbows form to help understand if they really do bring good fortune.
Rainbows in Mythology and Folklore
Rainbows have played an important role in the myths and folklore of many cultures throughout history. In ancient Greek mythology, the goddess Iris was thought to use rainbows to bridge a path between heaven and earth. Seeing a rainbow was seen as a message from the gods and a good omen. In Irish folklore, leprechauns were said to hide their pot of gold treasure at the end of a rainbow. Trying to find this pot of gold was seen as bringing good luck. In Buddhism and Hinduism, rainbows are part of meditations and considered highly auspicious symbols. Rainbow imagery also appears in Australian aboriginal dreamtime stories as serpents bridging the human world and spirit worlds.
In many Native American traditions, rainbows have sacred meanings. For the ancient Navajo people, rainbows represented the union between Mother Earth and Father Sky, acting as a bridge between the physical and spiritual worlds. Spotting a rainbow was seen as a blessing and signal from the gods. Cherokee and Lakota tribes also viewed rainbows as paths where gods and ancestral spirits traveled between worlds. These are just a few examples of the extensive positive rainbow symbolism throughout mythology and indigenous cultures.
Rainbows also feature heavily in many ancient Chinese myths and legends. They were thought to be bridges created by the gods or celestial animals like dragons and phoenixes. Chinese tradition held that good fortune would come to those who saw a rainbow arching towards the earth rather than the heavens. Rainbow clouds and rainbow-colored auspicious lights or vapors were also seen as signs of blessing.
In the Abrahamic faiths like Judaism, Christianity, and Islam, rainbows took on symbolism from the story of Noah’s Ark. After the great flood, God placed a rainbow in the sky as a sign and covenant with Noah that never again would a flood destroy the Earth. Because of this biblical story, rainbows came to represent God’s benevolence, forgiveness, and hope.

Thanks to these myths and cultural histories, rainbows have continued to be seen as lucky, hopeful symbols in many parts of the world. There are a variety of folk beliefs and superstitions around rainbows bringing good fortune:

They are also auspicious wedding signs in places like Hawaii where starting a marriage under a rainbow is considered very fortunate. Rainbow imagery is ubiquitous on items like greeting cards, jewelry, and clothing to represent luck, blessings, and bright futures.
Of course, science may explain away some magical reasoning around rainbow luck. But rainbows can undeniably lift our spirits and inspire joyful feelings of hope. In psychology, seeing rainbows can have a positive uplifting effect and make people feel optimistic. So while they may not literally shower us in good fortune, rainbows certainly confer the inner gift of lighting up our mood!
How Rainbows Form Scientifically
To understand what makes a rainbow appear, we can look to physics and meteorology to explain the optical phenomenon scientifically. Here is a quick summary:
- Rainbows are created by sunlight interacting with water droplets in the air.
- Light from the sun enters the droplet and slows down as it passes through, separating into different wavelengths (colors).
- The light reflects off the back of the droplet and exits, refracting at a wider angle.
- This dispersed light spreads into the colorful spectrum we see as a rainbow.
- To see a rainbow, the sun must be behind you and rain or mist in front of you.
- The most vivid rainbows form when the sun is lower in the sky, like mornings and evenings.
- A rainbow’s arc forms from about 40-42° angle from your perspective.
- Double rainbows form from double internal reflections in the raindrops.
So in scientific terms, a rainbow requires the combination of sunlight and proper moisture conditions to refract the light. The appearance of a rainbow depends on the viewer’s specific position in relation to the sun’s location. While they never physically reach a fixed “end” point, spotting a rainbow can often seem like a magical coincidence and notable event.
Famous Rainbows in Culture
Rainbows have made notable appearances in culture, songs, and stories over the years. Here are some of the most famous rainbow events and Symbols:
- Dorothy’s ruby red slippers in The Wizard of Oz could magically transport her by clicking her heels together three times while reciting “There’s no place like home.”
- The Rainbow Flag, designed by Gilbert Baker in 1978, has become an international LGBTQ Pride and social movement symbol.
- “Somewhere Over the Rainbow” is Judy Garland’s iconic ballad in The Wizard of Oz film.
- Rainbow Brite is a cheerful animated character who brings color to the world using her magical rainbow belt.
- “Reading Rainbow” was an educational PBS TV series promoting literacy in children.
- Yogi Bear cartoons often featured the recurring gag of Yogi trying to steal picnic baskets while evading Ranger Smith.
Rainbows consistently capture our imaginations across cultures and serve as symbols of aspiration, creativity, individual expression, and community. Their beauty and mystique will likely continue inspiring art, stories, and wonder for generations to come.
