At every point before “white light” is interpreted as “white” in our brains, it is simply a combination of all colors.  In our eyes, there are rods and cones.  Rods exist to determine the intensity of light whereas cones exist to determine the color.  There are three cones in the eye (red, green, and blue).  They each detect wavelengths for of colors on the ROGYBV spectrum.  In order for our brains to register white light, all of the cones must be triggered at once, sending electrical messages to the brain.  This indicates that all colors and wavelengths are present.  For some reason, our brain registers the presence of all colors as being white.  Outside of our brains, white exists as the combination of every color.
