Wow! "Exploring Color" lived up to all of the 5-star reviews, and surpassed them all. I've never been able to say that about a book before. This book focuses mainly on the use of color in artwork -- why some color schemes work, and why others fail. Many other topics are covered and related to back to the use of color, such as composition, presentation, design and types of contrast. Example pictures are taken from a wide range of artwork in different mediums by various artists -- simply wonderful! After each description, the author inserts an exercise for the reader, to help you understand and apply the principle presented. These exercises can be done in any medium (watercolor, oil, pastel, cloth, etc.), and far surpass the "paint by number/follow me" exercises in books aimed at nervous beginners.
"Exploring Color " targets intermediate to advanced artists. Beginers should give it a chance, also. Try it, you'll be wowed.
