A photon.
A 'Photon' is an individual packet of electromagnetic energy that makes up electromagnetic radiation, a minimum discrete quantity of radiant energy.
A discrete quantity of energy that can be thought of as a packet of electromagnetic radiation traveling at the speed of light.
Simple explanation:
A pulse of electromagnetic radiation emitted when electrons drop from a higher to a lower energy level. Photons are light particles.
More especifically:
The indivisible unit, or quantum, of electro-magnetic radiation. The energy of the photons determines the nature of the radiation, from radio waves at the lowest energy levels, up through infra-red, visible, and ultra-violet light, to X-or gamma-rays, which have energy high enough to ionize atoms.
Colloquially, a "particle of light." Although light spreads as an electromagnetic wave, it can be created or absorbed only in discrete amounts of energy, known as photons. The energy of photons increases, the shorter the wavelength--smallest for radio waves, larger for visible light, largest for x-rays and gamma rays.

A photon.
In fact all electric and magnetic signals such as radio, UV, and IR use photons of differing energies. These energies ultimately determine the color. It just so happens that humans can only see the 400 nm to 700 nm wavelength photons.
