What does the acronym ROYGBIV help to remember?

The acronym ROYGBIV stands for the sequence of colors found in a rainbow: Red, Orange, Yellow, Green, Blue, Indigo, and Violet. This mnemonic helps people visualize and recall the order of these colors, which is especially useful in educational settings, art, and science when discussing light and wavelength. This systematic arrangement of colors is typically seen when light refracts through moisture in the atmosphere, creating a spectrum that has been commonly associated with rainbows. Using this acronym makes it easier to memorize the color sequence for various applications.
