Complementary colors are any two colors that are directly opposite to each other on the color wheel. For instance, using the color wheel chart, red is complementary to green. 

When we observe visible color using our eyes, the object is actually reflecting that color. When we see a red apple, the fruitis absorbing every color in the visible color spectrum besides red.Therefore, the only color being reflected is red, thus our eyes see that color.

- A black object is seen when the object absorbs every color inthe visible light spectrum and no light is reflected. An object appears white because it reflects all colors.

Using the color wheel, answer the questions. If we see a purple flower what color(s) does the flower absorb? What color iscomplementary to blue? If you have a white cloth, what colors areabsorbed and what is reflected? If you have a black car, what color does the car absorb and what is reflected?
