White is a shade, the perception of which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in nearly equal amounts and with high brightness compared to the surroundings. A white visual stimulation will be void of hue and grayness. White light can be generated in many ways. The sun is such a source, electric incandescence is another. Modern light sources are fluorescent lamps and light-emitting diodes. An object whose surface reflects back most of the light it receives and does not alter its color will appear white, unless it has very high specular reflection. Since white objects such as clouds, snow and flowers appear often in nature, human culture has many references to white, often related to purity and cleanness. The high contrast between white and black is used to represent opposites. In some Asian cultures, white is considered to be a color that represents death. White also represented death in ancient Egypt, representing the lifeless desert that covered much of the country; black was held to be the color of life, representing the mud-covered fertile lands created by the flooding of the Nile and giving the country its name (Kemet, or "black land").
