This month, the wallpaper was inspired by sapphire (September's birthstone) and harvests.
Sapphires as you may know are usually a deep blue, but are based in Corundum, and can come in a variety of colors...
"Rubies are corundum which contain chromium impurities that absorb yellow-green light and result in deeper ruby red color with increasing content. Purple sapphires contain trace amounts of vanadium and come in a variety of shades. Corundum that contains ~0.01% of titanium is colorless. If trace amounts of iron are present, a very pale yellow to green color may be seen. If both titanium and iron impurities are present together, however, the result is a magnificent deep-blue color."
Considering this, I composed this wallpaper using those very colors combined with gem-like, faceted patterning, and arial farm photos.
