What is the initial color of the traffic light?

GREEN
YELLOW
RED
None

The correct answer is: RED

The initial color of the traffic light is red because it is the first color in the typical traffic light sequence. The other options are incorrect because they are not the first color in the sequence. Green is paired with yellow to indicate "go" and "caution", while yellow is paired with red to indicate "caution" and "stop". Additionally, the option "None" is incorrect because it is not a color in the traditional traffic light sequence.
