The book itself is very well-designed and would make a great coffee table addition, but the content I did not like.
Firstly, all the colours featured are mostly dark schemes, because - as the author herself states - she loves dark hues, and black in particular. All the interiors pictured looked so gloomy, moody, small, cramped, dreary and awfully dark to me. If that's what you're looking for, then this book is for you.
Secondly, the author's opinions are not convincing at all. E.g. She tries to argue that dark-coloured interiors are help boost one's mood, as it did hers. The only thing I felt when viewing all those dark interiors was gloom and depression though. And she says the dark colours help make the rooms "cosy". Well, I didn't feel that at all. She then claims the dark colours "do not make the room look small", contrary to popular belief. I'm not buying that one either.
Thirdly, the author contradicts herself a great deal. E.g. She says the room should be well-lit and letting light in from windows is important. She then goes on to say that mirrors are important because they help disperse and add light to the room. But if light is so important, why choose such dark colours? In an already poorly-lit room, choosing such dark-coloured walls, ceilings and floors will only make the room look darker! I rolled my eyes at some of the interiors featured which showed open windows and mirrors in an attempt to make the room brighter, when the simple solution was NOT to choose such dark coloured walls, ceilings and floors in the first place! The lack of logic was so incredibly frustrating.
Lastly, I did not agree with a lot of the author's analyses of the interiors featured. E.g. Some of the furniture pieces she thinks are "opulent" or "elegant", I felt were excessive, comical or just plain ugly. Some colour combinations she thought were nice, I found to be off-putting. And for a room featured that was luxe-style but had a raw brick wall, she said that was a touch of genius; I thought it was awful and unfinished!
When it comes to design, things are subjective. I guess this book may still be useful in showing you what dark interiors look like and whether they are for you or not. For me, this book showed me what to avoid rather than embrace.
