Roy G. Biv

Roy G. Biv is a mnemonic device used to remember the sequence of colors in a rainbow: Red, Orange, Yellow, Green, Blue, Indigo, and Violet. These colors appear in the natural spectrum when light is refracted through water droplets or prisms, showing the visible light wavelength order. Each color transitions smoothly into the next, with Roy G. Biv serving as a helpful way to recall this pattern. This concept is useful in understanding light dispersion, optics, and the nature of color perception in the visible spectrum.
