How to style a black and white living room.

[WafflesOrIceCream]

Hello.
I have painted my lounge walls white silk.I wanted to incorporate some black accessories to match my black clock so I have brought a trendy black floor lamp.
Now I do not wish for it all to be black and white.I will be adding some green artificial plants.(I can not look after real plants!)
I wish to get a corner bookcase but not sure what colour.I'll show you some pictures of what I have in mind.I am open for suggestions.

Thank you.

The first one (all black) is my favourite. I love black accents with white / off-white, you just have to resist the urge to overdo it. What type of flooring do you have? What colour will the main items of furniture be? I really like blue-green as a secondary colour, with pops of something warmer, like antique gold or rust.

@ClematisBlue49 My doors are brown so I thought green would be a nice pop of colour.I could also incorporate a bit of gold maybe just to soften the look.I also have brown leather sofa's (for now).
