A lot of traffic lights in the US are actually "not just green".
The traffic lights have an abnormally high amount of blue light for being an overall green light, to help people with red-green colorblindness to tell the difference between the red and "green" light.
If you take a look at the green light on a dash cam, you might see that the color is abnormally bluer than what you might see in real life.
