Light travels in waves but also as little energy packets. A photon of light contains the entire visible outlook to the human eye: red, orange, yellow, green, blue, indigo and violet. Plants absorb red, orange, yellow, blue, indigo and violet wavelengths of light but reflect green. When wavelengths of light are absorbed, they are no longer available for eyes to see, which is why plants look green. Pigments also help this cause.
Plants with little light exposure grew taller because they are trying to reach the sun. They are also pale in color but change back to green when exposed to more light. But they also died out faster.
