Rainbows only occur in special conditions LGBT Rainbow Rains shirt after or during showery rain, with the sun in the line of sight from. the observer through the rainbow, giving a radial circular effect to the observer. The colours of the rainbow are caused by normal white light being split into the optical spectrum due to sunlight falling on water droplets at the right angle, undergoing internal reflection and passing out through the spherical raindrops so they act as tiny prisms to refract the light together. A primary rainbow occurs at a 42-degree angle. On rare occasions, there is a secondary rainbow at a larger degree angle behind it with the colors faint and reversed. It is even possible on very rare occasions to get a tertiary rainbow. To a terrestrial observer, the effect disappears as a bow behind the horizon, but looked at from altitude rainbows are seen to be circular. So there are no pots of gold anyway.

A true rainbow requires a spherical raindrop, and the LGBT Rainbow Rains shirt process is not at all like how a prism forms a spectrum. It is the relationship between the angles as the light enters the sphere, and reflects inside of it, that concentrates different colors at different angles. This shows a uniform set of rays entering the drop at the top, reflecting once, and exiting at the bottom. Notice how the rays drawn in red are close together as they exit the drop. This is what concentrates the colors into the familiar rainbow arc since it occurs at different angles for different colors. There is a phenomenon that is similar to a rainbow, called a halo, that is made by ice crystals. Notice how red is on the inside, not the outside, and it is seen in the direction of the sun. Halos are formed when, just like with a prism, all of the light of a single color deflects the same amount.
