It appears black. A green pigment can only reflect green light and red light is a primary colour, that is it contains only red.
When red light and green light shine on red curtains, the red curtains will appear red. This is because objects appear a certain color based on the wavelengths of light they reflect. Red objects reflect red light and absorb other colors, so even when green light is shone on them, they will still primarily reflect red light, maintaining their red appearance.

The same thing it does during the day.
A red light will be needed to combine with magenta light to produce green light. Green light is the complementary color to magenta, so by mixing red light with magenta light, the result will be green light.
It means you should stop and wait for a green light to go through the intersection.
It is yellow-- mixing red and green PAINT produces brown; mixing red and green LIGHT produces yellow.
When red light and green light are added together, yellow light is produced. This is because red and green light combine to stimulate both the red and green cones in our eyes, creating the perception of yellow.
Green light has higher energy than red light. This is because green light has a shorter wavelength and higher frequency compared to red light.
