Title: Repeat of Existing Knowledge
Review: This book does not contain anything new. All content has been published in hundreds if not thousands of other publications. A quick internet search will convince you of this. Also, the book is badly edited. Hundreds of repetitions of the same argument can be found. Also, the same exposition is repeated for every color. Unless you are writing for 5th graders such duplication is just a waste of paper. The whole thing is poorly executed. It was a waste of money.
