Query: black and white- seriously?

I was very excited to get this book as i collect gemstones. But let me ask you this: how can you appreciate gemstones in all their glory if this book is in black and white? are you serious? a description of brilliant green can not be done justice if everything is in shades of gray. This book is a waste of money unless you are using it as a text book. I'd return it if i felt like making the trek to the post office.
