  • Wavelengths and Colors of the Visible Spectrum

     · The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light or the visible spectrum because humans can see it.Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.
