Which color follows violet in the visible spectrum?

In the visible spectrum, colors are arranged according to their wavelengths, with violet having the shortest wavelength and red having the longest. Following violet, the next color in the spectrum is indigo. The sequence of colors in the visible light spectrum, often memorized with the acronym ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo, Violet), shows that indigo comes directly after violet.

This order is based on the way light refracts through a prism or is represented in a rainbow, where indigo continues from violet before transitioning to blue. Understanding the organization of the spectrum is essential for grasping topics related to light, color theory, and even aspects of vision and perception, which are relevant in various fields, including aesthetics and design, integral to CIDESCO certification studies.
