It is important to consider the environment you want you want to create for your living room. For this reason, factors such as the time you usually stay at home, or how much you like to let sunlight throught the windows, must be taken into account.
If you have a space with good sun exposure you can try earth or brown tones.
If, on the other hand, your space does not have enough lighting, you can try yellow or warmer tones that provide light.
Another great alternative is gray tones for a cool and relaxed type of environment. If your living room is usually used mostly at night, you can try cold tones.
