When blue and yellow paints are mixed together, the result is green. The reason for this is that
blue and yellow are complementary colors.
yellow pigments absorb green light and reflect all the others.
blue reflects only blue light, and yellow reflects almost all colors of light.

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.
