White is the lightest colour and is achromatic (having no hue). It is the colour of fresh snow, chalk and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue and green light. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore a white toga as a symbol of citizenship. In the Middle Ages and Renaissance a white unicorn symbolised chastity, and a white lamb sacrifice and purity. It was the royal colour of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). According to surveys in Europe and the United States, white is the colour most often associated with perfection, the good, honesty, cleanliness, the beginning, the new, neutrality, and exactitude. White is an important colour for almost all world religions.
