If an object absorbs light of most visible frequencies (absorbs because the light's frequency matches electron's frequency), and reflects red, for example, the object appears red. (reflect because red falls below or above the electron's natural frequencies).
The human eye is not capable of seeing radiation with wavelengths outside the visible spectrum. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum. Black is a total absence of light. Earth's most important energy source is the Sun. Sunlight consists of the entire electromagnetic spectrum.
