I was sure I would love Color Index XL when I chose to review it. I was so excited I barely looked at the other offerings. Sadly, I was disappointed. The book is an odd size and kind of a paperback but not quite. Definitely not a hardcover. A huge amount of colors as you would expect. But the pages are too small. Hard for any color to really jump up at you. The color harmony section was entertaining. Young art students and those working in fabric might benefit the most from this book.
