What is light ? Light is the region of the electromagnetic spectrum which the unaided human eye can perceive. On the blue (short wavelength) end, the limit is rather sharp and we can put it at a wavelength of 390nm (a frequency of 770THz) for extreme violet. On the red (long wavelength) end, the limit is not as clear-cut, but it can be set around 700nm (430THz) for extreme red. Waves with higher frequency than extreme violet are called ultraviolet, and those with lower frequency than extreme red are called infrared...

When a designer is utilizing the computer to generate digital media, colors are achieved with the additive color method.
