Study in Green and Lavender is another study in color harmony.  You may not know this but lavender class is what happens when a glass bottle is exposed to the elements over decades.  Back in the days before trash pickup, farmers and ranchers would have their own trash pile.  The bottles would age in the sun to a beautiful lavender.  Those not used for target practice have made it to the antique stores.  I love the patina.
