So here is a cool little tip which I've published in years past....I have used this so many times. Often a photograph is hard to break down into specific colors....especially those involving nature. The website CSS Drive Image to Colors Palette Generator will do that for you. Above you see my photo (below left) which has been uploaded to their page...you click on a button and within seconds, they break your photo down for you AND in different values....how cool is that. The official site is http://www.cssdrive.com/imagepalette/ Give it a try.
