WebbHumans perceive purple as a range of color that falls between blue and red on the visible light spectrum. Our brains interpret the wavelengths of light that fall within the range of approximately 380 to 450 nanometers as purple. To fully understand perception of purple, it is important to understand how the human eye works.
