What "color" (that is actually not a color at all) is associated with the absence of light?
- Correct Answer: black
- clear
- opaque
- grey
Explanation: The color of light that strikes an object may also affect the color that the object appears. For example, if only blue light strikes a red apple, the blue light is absorbed and no light is reflected. When no light reflects from an object, it looks black. Black isn’t a color. It is the absence of light.
