Today afternoon,I have been seeing this book while waiting for my friend.it introduce the original of art and the different kinds of paintings.One  part that is talking about color are my favorite.there is a  rich blue made out of ultramarine. It's very vivid and gorgeous and rich.ultramarine is gemstone and more expensive than gold.You must can't believe it that purple is made out of sunflower.crushed sunflower seeds made the lilac shade of the color purple.
