What Wavelength Goes With a Color? Colors We Can't See There are many wavelengths in the electromagnetic spectrum the human eye cannot detect.
Energy with wavelengths too short for humans to see Energy with wavelengths too short to see is "bluer than blue". 5/4/94 - Why are different things different colors? (Lansing State Journal, May 4, 1994) When different wavelengths of light hit our eyes, we see different colors.
Light from the sun or light bulbs has many different wavelengths. This great mixture of wavelengths is commonly perceived as white. If the light hits an object - a road, tree, house, anything really - the object absorbs some wavelengths. Other wavelengths are reflected, and those are the ones we see.
