There must be a light to illuminate the object.
White light contains many different colors of light.
This can be seen by observing how sunlight is broken into its components when passed through a prism. Each color of light has a particular wavelength. An object appears to be a certain color because it has pigments that absorb some of the wavelengths of the light that illuminates it while reflecting others back to the eye.
