- While there is no pure purple wavelength of light, there are some naturally occurring pigments that selectively absorb certain wavelengths to appear purple. Magenta, rose, and purple are considered "extra-spectral colors" and are not found in the visible spectrum of light123. However, we can perceive purple through various natural phenomena, such as the violet flash at sunset, the twilight sky, or the indigo bands of a rainbow4.
