Orange Red is a magic color. You can mix all shades of reds from madder to strawberry if you include a bit of Orange red in the mix...maybe there is a magic green too. I sort my out my greens by yellow and black...some greens have a bit of yellow, lime, Kelly, and some have a bit of black, avocado, forest. You can mix all black/greens together with harmony and so also with all yellow greens. Go to the paint department of your local box store and gather up as many green paint chips as you can. Then go play with mixing green tones and tints to your hearts content and you will learn something about color theory. Also if you want a gorgeous mix here is one I have found...lime, avocado, forest greens mixed with dark chocolate brown. I brown is you major color then the greens smile and play nice.
