      This has to do with the way the sun is reflected! So the sun reflects blue light and grass reflects green light!

      Chemicals in the air absorb more red than blue from the sun, so the sky looks blue! The blue is reflected back to us and we can see the blue. With grass, plants have a compound called chlorophyll, which absorbs red and blue and reflects back green light. Chlorophyll is what gives the plants energy!
