Material in an object that selectively absorbs colored light is called a pigment.
Two colors of light that add together to form black light are complementary colors.
A spectroscope is an instrument that analyzes the colors in a light beam.
Some electrons in atoms vibrate at a characteristic frequency that produces white light.
If an object were completely black, you wouldn't be able to see it directly.
