Why dose a white piece of paper appear white in white light,red in red light,blue in blue light and so on for all colors?

• physics -

White objects reflect a high and nearly equal percentage of the incident light intensity, at all wavelengths that illuminate them. Thus thay take on the color of the illuminating light source.
