I love art but was told about it, never taught. This practical book taught me how to teach myself and others. It prevents amateur behaviour in art and for those interested in how to decorate your home, it's an absolute must. It methodically took me through tonal ranges in a way that I and others easily grasp. It's an "Oh so that's how to do it", kind of book. It demonstrates how to lighten and darken color without using black and white, thereby keeping the color's vibrancy. And now, I finally understand why I like what I do. In all, I would highly recommend the usefulness of this book and refer to it often.
