The total number of colors in a rainbow is typically described as seven. These colors, often remembered by the acronym ROYGBIV, include Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Rainbows are a meteorological phenomenon caused by the refraction, dispersion, and reflection of light, usually seen when sunlight interacts with moisture in the atmosphere, such as during or after rain. Each color seamlessly transitions into the next, creating a spectrum. The appearance of a rainbow has inspired numerous cultural interpretations and is often associated with hope and beauty, serving as a natural symbol of connection and diversity in nature.
