Accent walls are always going to be around. I am just not sure that a red wall amidst the green walls is going to get you what you want.

Instead, I would focus on bringing in interest art with some of the red you love in it - it certainly is not about matching, but if you find art or wall decor that speaks to you and contains the color, then you are set.

What about your window treatments - perhaps a stripe or print that has an interesting pattern and all your colors.

You could hang a single large piece of art over the bed that will enliven the focal area.

Consider lamps, perhaps handpainted ceramic of some kind, that can bring in some interest. An area rug under the bed could work, too. A vase of interesting greenery and florals can add a spark.

The other thing that you might consider is having mirrors cut for the tops of the nightstands, with polished edges. It will bounce light and break up some of the dark furniture feel. If the hardware on the furniture is changeable, consider that as another way to add new life to the dark furniture.

I don't think I'd do a red wall with three green walls. Les gave you some good ideas. Looking forward to seeing pictures!

I like to look at pics of rooms done by eminent designers and seldom do I see accent walls. What I've read designers say about accent walls is that there must be a good reason for them. I suspect most amateur decorators think an accent wall will solve a problem with their room without even understanding what the problem is.

What I might do is embrace the dark and instead of white bedding do burgundy bedspread and drapes, and perhaps even put a dark area rug over part of the lighter w2w.

I like what Les said, her advice is always good!

I think accent walls aren't out as much as designers would like to say they are. They are an easy way to bring a little interest to a space especially when it's lacking in other architectural details. That said, I do agree with Les. Red is a very strong color and instead of enhancing the room, a whole wall of it will completely take it over.

Red is great accent color and will look pretty with the green, but you don't need a lot of it for it to be relevant. It's like using black in a room. The smallest amount will be visible and speak volumes. The greens in the photos below are not sage but they can still show you how the red impacts each room and which is more pleasing to the eye and I hope they help you to understand what we're trying to convey.
