Under the green light, the color becomes lighter, the green becomes lighter, the green becomes lighter, the Yellow becomes greenish yellow, the red becomes black, and the white turns green. Under the yellow light, the Yellow becomes pale, the magenta turns red, the green turns green, the blue becomes black, the white becomes yellow. Under the blue light, the color is lighter, the blue becomes lighter, the green becomes lighter, the green becomes darker, the Yellow becomes black, and the white becomes blue.
