On Earth, the plant pigment chlorophyll absorbs the most abundant and highest - energy
colors that
reach the
planet's surface — red and blue, respectively — while reflecting green, giving vegetation its
color.
If comparatively more bluish or reddish light
reaches a
planet's surface than on Earth, photosynthetic plant - type life may may not be greenish in
color, because such life will have evolved to different pigments in order to optimize their use of available and so
color the appearance of the
planet's land surfaces accordingly.
