If you are painting, mix yellow, a little bit of red, a little bit of black. Mix them together and paint a tree. Not on a tree, on a painting board or canvas. If you are cooking as I just read, you buy a product called Parisian Browning essence made by a company called Queen Fine Foods made in Australia. They might have it in America under a different brand.
