Why is grass green?
Now, grass is green because it has chlorophyll. But the question why is chlorophyll green and for that you have one answer: Because the color green is pleasing to the eye.
You know, some colors like red are difficult to view for some time. But green, you can continue to look at it and it’s soothing to the eye. And so grass, which grows in abundance, is green because that’s the color that is easy for the eye to cope with.
Now why is green soothing to the eye? This, don’t expect me to answer.
