Green is one of my favorite colors, especially in decor (I've painted two bedrooms green) and while I think it is a great wall color, it's also a fun color to use as an accent color in an otherwise simple or neutral room.
Here are some of my favorite rooms with green accents.
The green curtains in this grey dining room are to die for.
There is a lot going on in this living room, but my eye goes right to that green ottoman. I would put that into my living room in a heartbeat!
I love how this green velvet chaise adds a touch of glamour to this otherwise rustic feeling bedroom.
