Despite their obvious placements on top or bottom of a traffic light, traces of orange and blue are added to the red and green lights to aid those with red-green color blindness to distinguish between the two.
This only affects red-green color blind people. The order of the colors never change. Someone who is colorblind knows it is red on top, yellow in the middle, and green on the bottom. Blue is added to a green traffic light and orange added to a red traffic light. Next time you are out and about, look at the traffic lights. I know in Miami some green traffic lights have a distinct blue undertone, but not all of them have this same undertone. You can also do an image search on a search engine to see what I am talking about.
