This is the feeling that comes to mind when I look outside: warm tones! It can be acheived with paint, furnishings, textures.. In short, it is easy to create a space that will feel warm and cozy! Remember: North facing rooms always have very little light and is usually a cold one. So stay away from grays, and green based paint colours. South facing rooms will embrace warm tones very well, as well as west facing rooms! Have fun!
