While Luke's lightsaber might have been the inspiration, I quickly developed rationale that further cemented green as my favorite. To me, green is the color of nature. The spouting of green leaves and grass is our signal that spring (my favorite season) has come. Kermit, my favorite muppet, is green and sings of that fact. Green was often the color worn by our military, which I wanted to join when I was younger. It is the color used by our stoplights to indicate that it's time to move. It is the primary color of our currency in the U.S. It is one of the colors of Christmas. Currently, it is the color of my winter coat, my computer bag, my Franklin planner (which I no longer use), and my cellphone case (although all of those are more of an olive green rather than the deeper green that I prefer). It is also the color of ink in which I do most of my grading.
Now, I like other colors (well, yellow and I have our issues) and have no problem with wearing them or having them on the items around me. For that matter, if one were to take inventory of my clothes, it would be easy to guess that my preferred color is blue (which comes in second). Still, green, expecially the green of leaves in spring, is my favorite.
