Why some trees do not have green leaves?
Or why much of trees have green leaves?
It's all due to the pigments. Most trees have green leaves because of chlorophyll, a photosynthetic molecule that contains pigment that reflects green light. During fall and winter, the cholorphyll is stored outside of the leaves so that it is not wasted when the leaves fall. Then more pigment containing molecules called flavonoids and anthocyanins are left behind in the leaves, creating an orange or red color respectively. So the concentration of certain pigments is going to determine the color of the leaves.
Many underwater plants do not have green leaves (seaweed etc.) because they contain carotenes and xanthophylls (more red/orange) in place of the green pigment, chlorophyll. This enables them to absorb more light from the green and blue parts of the visible spectrum. This is beneficial as green, blue and yellow light (medium wavelength) is able to penetrate water to greater depths than red/orange (long wavelenth) and violet (short wavelength) light can.
