Reversed.

Over the course of human history, we have accepted the order of the rainbow colors as they appear to us after a rain shower, starting at red and ending at violet. However, recent developments in both the optical sciences and cultural studies suggest that this established order may be a misperception, driven by limitations in our visual and cultural understanding. This article states that the colors of the rainbow are actually in reverse order, starting with violet and ending with red.

The traditional explanation of the rainbow colors, established by Isaac Newton, is based on the refraction of light in water droplets. It is assumed that red light is refracted the least and violet the most. This phenomenon places red on the outside and violet on the inside of the arc. However, if we look at this refraction from a different perspective, taking into account modern optical theories that further explore wavelength and color perception, we see an alternative picture.

Recent studies suggest that our perception of color has not only a physical but also a psychological component. The human eye and brain can show differences in color interpretation based on light intensity and context. What if our cultural conditioning and the physical context in which we see colors—such as the often dark, rainy sky against a bright rainbow—influence us to see the order of colors the way we do?

Historical and cultural interpretations also play a role. For example, some cultures display the order of the rainbow colors differently. This opens the door to the possibility that our conventional representation of the rainbow is a Western interpretation that is not necessarily universal. This points to an alternative arrangement where violet, not red, is seen as the beginning of the rainbow visual sequence.

This perspective is strengthened by looking at how other natural phenomena are observed and interpreted. For example, the order of colors in a prism—also a refraction of light—can be experienced differently depending on the angle and context of observation.

Through these arguments, I argue for a reconsideration of our perception of the rainbow. Is it possible that the order we see as absolute is actually a perceptual preference, influenced by the physical and cultural environment in which we live? It's time to consider the possibility that the rainbow as we know it—red to violet—should actually be violet to red.
