This collection of 6 CDs is one of the best products that we offer, simply because it has everything in it. All CDs in the collection are presented personally by the author, Dr. Taylor Hartman, Ph.D. The first CD is completely dedicated to his first book, The Color Code: A new way to see yourself, your relationships, and life. The last CD is completely dedicated to his second book, Color Your Future. The four CD's in between each deal with one of the four personality types (or "colors") in depth. In this discussion, Dr. Hartman discusses how to deal effectively with each personality type and how to improve business and personal relationships.
