The color with the longest wavelength in the visible spectrum is red, which ranges from about 620 to 750 nanometers. Wavelengths longer than red fall into the infrared spectrum, which is not visible to the human eye. As the wavelength increases, the color shifts through the spectrum, with red representing the longest visible wavelength.
