If you're thinking about what are the best colors for north-facing rooms, then you're already ahead of the game. The direction a room faces and the resulting quality of the natural light can have quite an effect on how colors will read, so it's a good idea to consider this when planning your interior design.
North-facing rooms tend to feature a cooler, fresher light, but how you deal with that is a matter of personal preference. Some people will be looking to introduce warmth and brightness to their colors to create warm color schemes for north-facing rooms, while others will look to enhance the cooler look and embrace it with shades from the colder side of the color wheel to create cool color schemes.
