The set of Wavelength is absorbed by pigment. So in a typical leaf some pigment can’t be visible.
Step-by-step explanation:
There are mainly three types of key pigments in photosynthesis. These three key pigments are Chlorophyll a, Chlorophyll b, and β-carotene. Those set of wavelengths which is not absorbed by pigment and finally it is reflected and that reflected light is what we see as a color.
The reason behind color of plant looking green because it contains huge amount of chlorophyll a and b molecule. It reflects the green light.
