๐Rainbow
A rainbow is sunlight bent and split inside countless water droplets, painting an arc of color across the sky. The basic physics was first nailed down by Isaac Newton around 1666, when he used a prism in his Cambridge room to show that white light is actually a mix of colors, traditionally counted as seven: red, orange, yellow, green, blue, indigo and violet. In a real rainbow, light enters a raindrop, refracts, reflects off the back of the drop and refracts again on the way out, leaving the drop at an angle of about 42 degrees from the original beam. Multiply that across millions of drops and the result is the arc you see opposite the Sun. Beyond the optics, rainbows are one of the most universal good-vibe symbols on Earth. They appear in the Bible, in Greek myth with the goddess Iris, in Japanese folklore as a bridge, on the LGBTQ+ pride flag and on every kids' show ever made. On moomz, rainbow polls do extremely well because they slot into nature, identity, aesthetic and pride conversations all at once. This page collects the most popular questions: favorite color, best rainbow memory, real rainbow or filter, and which emoji rainbow hits hardest.
The physics behind a rainbow
Rainbows are essentially nature's free prism. White sunlight is a mix of all visible wavelengths. When it enters a raindrop, each wavelength refracts at a slightly different angle because the speed of light changes more for shorter (blue) wavelengths than longer (red) ones. Inside the drop, the light reflects off the back surface, then refracts again on the way out. The result is a fan of colors, with red on the outer edge of the arc and violet on the inner edge, at angles around 40 to 42 degrees from the antisolar point. To see a rainbow, the Sun has to be behind you and rain or mist in front of you. Double rainbows appear when light reflects twice inside drops; the secondary arc is dimmer and reversed in color order. Supernumerary bows, faint pink and green fringes inside the main arc, show up when drops are very uniform in size. Moonbows, lit by full-moon light, are real but very faint. Rainbows are actually full circles when viewed from a plane, with the horizon usually clipping the bottom half from the ground.
Rainbows in myth, pride and pop culture
Almost every culture has a rainbow story. In Norse myth, Bifrost is a rainbow bridge between Asgard and the mortal world. The Greek goddess Iris travels along rainbows as a messenger. In the Bible, the rainbow is the sign of God's promise after the flood. Many indigenous traditions associate rainbows with spirits or transitions between worlds. In modern culture, the rainbow has become a powerful symbol of LGBTQ+ pride since Gilbert Baker designed the original eight-stripe flag in 1978. Companies love to slap rainbows on logos every June, which has its own internet drama. The Wizard of Oz Over the Rainbow song, the Mario rainbow road, the Apple logo of the 70s and 80s, all part of the rainbow visual canon. On moomz, rainbow polls work across age groups and ideologies, partly because the symbol is positive in nearly every culture but also because it can be a stand-in for pride, weather magic or just a vibe.
Rainbow polls that always crush on moomz
The most engaging rainbow polls combine aesthetics with identity. Favorite color in the rainbow, especially when forced to pick one. Real rainbow IRL or sunset more magical. Have you ever seen a double rainbow. Best use of rainbow as a symbol: pride flag, fairy tales, kid show or weather magic. Polls about photography work too: rainbow over a city, beach or mountains. Pride-themed polls always trend in June, and they can pair beautifully with travel or identity topics, like best pride city in the world (Madrid, NYC, Sao Paulo, Berlin, Sydney). On moomz, rainbow polls also peak after storms, when actual rainbows are most likely. Visual tip: a multicolor gradient header, a rainbow emoji and a clean either-or do the trick. Avoid making the poll heavy or political unless that is intentionally the point.

Frequently asked
Q.Why are there seven colors in a rainbow?+
Seven is a cultural choice, not a physical limit. Newton originally divided the visible spectrum into five colors, then added orange and indigo to bring the count up to seven, partly to match musical notes and other classical sevens. In reality, the spectrum is continuous: red blends into orange, orange into yellow and so on, with no hard boundaries. Some cultures count five or six colors instead. The seven-color count just stuck in English-speaking education and is now baked into kids' songs and storybooks everywhere.
Q.Who discovered how rainbows work?+
The first solid scientific explanation came from Isaac Newton, who showed in 1666 that a prism could split white light into a spectrum of colors and then recombine that spectrum into white light. He extended this idea to rainbows. Earlier thinkers like Theodoric of Freiberg in the 14th century had already worked out parts of the geometry inside a raindrop. Descartes refined the math in the 1600s. Modern optics fully describes rainbows using wave theory, including phenomena like supernumerary bows that simple ray tracing cannot explain.
Q.What is a double rainbow?+
A double rainbow happens when sunlight reflects twice inside each raindrop before leaving. The primary bow shows red on the outside and violet on the inside. The secondary bow, dimmer and a bit higher in the sky, has its colors reversed: red on the inside and violet on the outside. The gap between them, called Alexander's band, often looks darker than the surrounding sky because no light is reflected at those angles. Triple and quadruple rainbows exist too but are extremely rare and usually too faint to see without special equipment.
Q.Why are rainbows linked to pride?+
The rainbow became the symbol of LGBTQ+ pride thanks to artist Gilbert Baker, who designed the original rainbow flag for San Francisco's Gay Freedom Day in 1978. He chose the rainbow to represent diversity within the community: different colors, one flag. The original had eight stripes, later reduced to six for production reasons. Variations like the Progress flag now add more stripes to represent transgender people and people of color. On moomz, pride polls trend strongly in June but also year-round around big LGBTQ+ moments and debates.
