Why are leaves green in color 3?

The leaves of most plants are green, because the leaves are full of chemicals that are green.

Purple leaves are usually caused by a pigment called anthocyanin. Anthocyanin absorbs green and yellow light, causing them to appear deep red or purple to our eye. These leaves still contain chlorophyll, or else they couldn’t photosynthesise, but the green colouration is masked by the strong anthocyanin pigmentation.
