4. Three different cones were used to perceive color. How do they work?

a. They add together to create a perception of color

b. None of the response choices are correct

c. They subtract to create color perception

d. They allow you to differentiate color at 3 different parts of the spectrum

5. Why does color blindness come in pairs (red-green, blue-yellow)?
