Allow me to demonstrate why black and white color combinations work best with another color in the mix: I present the following rooms that Mobileffe is currently showing.
It's not the warmest-looking room in the world, but it still looks inviting. Still, I'm not sure what to think about the glowing rock-like things in the foreground. They might be radioactive.
There's only one other color here. That's all it takes to make this look work. Some warm wood tones soften the overall appearance, and add a nice organic counterpart.
The dog is another design reminder: if your current dog clashes with your decor, you MUST get a new one. (kidding, kidding)
This room somehow manages to be the chemical opposite of Prozac. Maybe it's the fact that the stripes look like jail bars. Even with the TV, this looks like a room in which fun is outlawed.
Thanks to contemporist for the inspiration.
