White is the lightest color and is achromatic. It is the color 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 everyday life, whiteness is often conferred with white pigments, especially titanium dioxide, of which is produced more than 3,000,000 tons per year.
