Visible light
A typical human eye can see light from 400nm to 700nm on the electromagnetic spectrum. This range is called ‘visible light’. Not all colors that humans can distinguish are in the visible spectrum; for example, pink is not included as it is a mix of multiple visible spectrum colors.
Some species can see light that is not in the visible spectrum. Bees can see ultraviolet light this helps them navigate to seek out nectar in flowers, many other insects and birds can also see ultraviolet light.
