C. Absorbtion vs. Reflection
-absorbtion is known as the colors of the visible light spectrum 
which are absorbed by a pigment. Something that appears red in the 
sunlight absorbs all the other colors other than red which is reflected 
and seen.
-Reflection is known as the colors of the visible light spectrum 
which are reflected by a pigment. Something that appears red in the 
sunlight absorbs all the other colors other than red which is reflected 
and seen.
D. Artificial Lighting
-the use of artificial lights give off some of the colors of the 
spectrum so things which may look a certain color in sunlight will look 
different or with a lack of color in artificial light. Halogen lights 
use multiple gasses which give off the entire color spectrum so it acts 
as white light or natural light.
