• Infrared light in the portion of the spectrum where it is still visible to humans (out to approximately 1050 nanometers) appears ruby red. Starting at about 660 nm in the visible red, a monochromatic source such as an LED or laser begins to look very slightly purplish, gradually becoming more so as the wavelength increases. Below about 900 nm, the color is more purple than red, similar to some of the color samples on this page.
