Rainbow

light · weather · colors

Light gets bent. Sunlight bends, bounces, and splits apart inside tiny water droplets, spreading into a band of colors we call a rainbow.

Always opposite the sun. A rainbow always appears in the part of the sky directly opposite the sun, so the sun is always behind you when you see one.

Not just rain. Rainbows can form in mist, spray from waterfalls, and even airborne dew, anywhere there are floating water droplets and sunshine.

Secretly a circle. A rainbow is actually a full circle of color, but the ground usually hides the bottom half so we only see an arc.

A smooth spectrum. The colors blend together in a continuous spectrum, flowing from red on the outside to violet on the inside.
