The most obvious is to pick one of the soft greens or soft blues from the pillow and then find a slightly grayed down version for the walls. Do you have a favorite color? Do you like subdued color or bright color? Neutrals?

You also have a bright yellow in the pillow, but I think I'd save that for accents, not walls.

One note: your furniture is very modern, but your curtains, both in style and fabric, say "traditional". Window treatments are expensive, but I'd like to see something like a plain panel (Ikea?) with clip-on rings or ones that come with tabs on the back for a rod (not country style tab tops). Ikea also has panels that are longer than most stores carry. I'd put the rod at the top of the frame or even higher if you get panels long enough.
An alternative would be simple fabric roman shades or even mini blinds to go with your modern style.

saypoint,

I was thinking about painting the walls some neutral shade but I am not completely set on that. I am open to trying out some bright color.

I was thinking about BM Silver Fox or Revere Pewter both of which are very popular on this forum. My home has an open floor plan and I can't find other colors which I can use in the adjoining spaces with these colors.

Regarding the curtains you see in the photo's, they are the old curtains which the previous owners left behind. My new curtains are in the fabric sample that I have in one of the photo's and they are grommet top which will go up on curtain rods. Unfortunately I already have them made (though I do agree that they are more classic looking than modern) but have spent a fortune on them already and don't have the budget to change them at this moment. The new curtains will go up after the paint is done. Also, the new curtains will go on much higher almost under the crown molding.

sloyd, I think hillside green looks pretty. Will run it by DH tonight.

Thank you both for your helpful suggestions.

Whatever I did, I woud do a cool color to balance the warmth of the brown and wood material.

I just painted my study BM Chelsea Gray. It's a lovely neutral and would be beautiful in your room.

Thanks for your suggestion. My question to you is that if I use a cool color in this room, can I use a warm color in the adjoining space (open floor plan).

Homeagain: I love the color you suggested but am worried that it would make the room very dark. Is it possible to please post a picture of your study so I can visualize it in a room.

Thanks!

Martha Stewart for Home Depot, "Sharkey Grey." I would def do it from top to bottom, woodwork too, to keep the contemporary feel. BTW ,love the sofa and chairs! Also, I strongly agree with Saypoint, about the curtains. Def go with something more tailored and organic. Can't wait to see what you choose!

Here's a photo of a beautiful color that works wonderfully with your colors. It's named Whythe Blue by BM,

Your furnishings are very modern, and I feel that the chair rail that's in the room leans toward the traditional. If possible, I'd remove the chair rail before painting. Personally, I'm not crazy about the fabric you've selected for curtains, I don't feel it works that well with your furnishings or your future palate. I'd go with something more organic and simple.

Here's a pic of my color suggestion prior post.

Here's a link to my thread when I first painted the room Chelsea Gray. I thought it would be dark also based on the photos I've seen of it online but in my space it is really more of a medium gray color. I'll take some more photos when I'm finished re-styling the room.
