This room has been this colour green now for well over a year which for me is quite the success story. I love green but with a north east facing living room, it can look colder on a dark day so that's why I went for a more muted green shade and paired it with greys and brown wood. In the evening make sure to have the correct ambient lighting to warm up the space for that more cozy feel. It's so important to know which way your room faces to help with your colour choice but at the end of the day, I always advocate going with what you love as that will always work. A little bit about the colour green... it relates to balance and harmony from a colour psychology perspective, it is the great balancer of the heart and the emotions, creating equilibrium between the head and the heart. From a meaning of colours perspective, green is also the colour of growth, the colour of spring, of renewal and rebirth. No wonder I like it x
