Question

Why does chlorophyll appears green?

Answer 1

Chlorophyll is a green pigment that gives most plants their color.The reason that it is green is because it absorbs other colors of light such as red and blue, so in a way the green light is reflected out since the pigment does not absorb it.

You probably know the colors of the spectrum (Red, Orange, Yellow, Green, Blue, Indigo, Violet); well, those colors are in ascending order of energy -- a photon of blue light has more energy than a photon of red light.

A particular pigment molecule (like chlorophyll) is specialized for absorbing a particular color of light and converting the light energy into the appropriate amount of chemical energy for making a chemical bond. Chlorophyll just absorbs blue and red light; it hardly absorbs any green light at all, so the green gets reflected back to our eyes, which is why leaves appear green.
