I find this a great book. Naturally it's not the first book one would pick up when learning to paint. As someone already said, do your homework, learn to mix colors and all the other things beginning artists need to learn before jumping into this book.I've even experimented a little with these techniques using acrylics, so you don't actually HAVE to use the book's formulas to learn new techniques. The results aren't as beautiful as oils, but it's still a good learning exercise.
