Why magenta does not exist in the visible rainbow
In short: Science presenter Steve Mould investigates how our eyes and brains create colors that physics cannot provide, specifically exploring why the color magenta is missing from the spectrum.
The video explores how human biology, rather than physics, dictates our perception of color. While the rainbow contains a spectrum of wavelengths, the cone cells in our eyes are only sensitive to red, green, and blue light. This creates a biological mystery: how can we perceive a color like magenta when it has no specific wavelength of its own?
By using colored torches, Mould demonstrates how our brains interpret the combination of these three primary colors to construct a much wider palette of experiences, effectively fooling our perception through the way our visual system processes light.
