Rainbows, the colorful arcs of light that grace the sky after rainfall or in certain atmospheric conditions. They are formed when sunlight is refracted, or bent, as it passes through water droplets in the air. This refraction causes the different colors of light to separate and create a beautiful spectrum of hues. Rainbows are often associated with positivity, hope, and wonder, captivating both young and old with their enchanting display of colors against the backdrop of the sky.
