He is right. Nature's shades of green are so beautiful, but especially these shades. This color of green is more than a hue. It shows the hard work, diligence and commitment these men have had to grow their crops, especially in the midst of a drought. The straight continuous lines of sprouting grain give hope of a new harvest. I think mostly this kind of green means success and satisfaction.
I guess we like to GO GREEN after all, just not the green most think of.
