What is the next color change after GREEN?

GREEN
YELLOW
RED
None

The correct answer is: YELLOW

After green, the traffic light typically changes to yellow before turning red. Yellow serves as a caution that the light is about to change and allows drivers to prepare to stop. Option C, red, is incorrect as it is not the next color after green. Option A, also green, would be incorrect as the question is asking for the next color change, not the current color. Option D, none, is also incorrect as there is always a next color after green in a standard traffic light sequence.
