Rainbows form when sunlight enters suspended water droplets after rain, slows down, and bends as it moves from air into denser water. The light reflects off the back of each droplet, exits, and separates into the full color spectrum because different wavelengths bend at different angles. Violet bends the most and red bends the least, which is why the colors always appear in the same order.
Every rainbow is unique to the person watching it. You and someone standing nearby are seeing light from entirely different droplets at slightly different angles, meaning no two people ever see the exact same rainbow. It is not a fixed object in the sky but an optical relationship between sunlight, water droplets, and your specific position.
Photographing a rainbow at the moment it appears requires precise conditions. The sun must be behind the photographer at less than 42 degrees above the horizon, with water droplets ahead. Sunrise and sunset produce the most dramatic versions because the darker sky provides contrast. As Al and generative tools make visual effects easier to replicate, moments like these serve as a reminder that some of the most compelling imagery still comes from understanding the physics behind natural light.

The promise of God not to flood the earth again!
Right place at the right time
I’ve never seen that.. beautiful; thank you for sharing
It’s not magic, it’s the promise of God! 🙌❤️
Ah the dome lighting up
What a beautiful firmament reflection!!!!👀
The Rainbow is Gods visual covenant & reminder = Gensis 9:12-17
Definitely a reflection from the dome!
This is seen in the wide open spaces of New Zealand quite frequently. A similar phenomenon can be created by water coming out of a garden hose - on a smaller scale, of course.
Not magic, it’s God’s blessing and promise.
This A.I. is so bad It's comical !
Exposing the FACT we live under a Dome.
I could imagine if Noah had the same experience
That's all I needed to see and now I know. IYKYK God is great!
Moon rising angled facing us, during the day. Keep asking questions..never settle for someone's else answers.
