May we see the room, please? Take pix from all corners to the opposite side. Comment here and use the photo button to upload more. Where is the bay window? What other walls are there? It appears the issue is the oversized sofa and hassock meant for a much larger space.

What we need are more distant shots from different angles....from all the corners. You're too close. I agree with changing out the drapes which have a feminine, lightweight appearance...not great with that heavy looking stone FP. I wouldn't look to a yellow in this room. Doesn't do a thing for that sofa or FP. As a pillow accent it's one thing, on the wall quite another! You have a pretty neutral slate here so there's plenty of options.

Your art is kinda neat but it's movement and colors are really fighting with the FP. With a busy pattern such as stone simple prints framed and matted work well. The matt separates the print from the busyness of the stone.

So, more pix please?

I'm afraid the curtains are a miss as they clash with the tones in the fireplace and the painting. The stand the TV is on looks messy and the lower part should be enclosed to hide all those electronic workings. The pouf may be comfortable but is unfortunately not attractive, with more leather than the room can accommodate. A glass and metal coffee table would open up that space. An important step is to obtain a large rug that will tie this area together. With the blue wall an Oriental tribal rug that has blue and beige or cream might be an idea. I usually prefer drapes, but with your windows white blinds would be a better idea. Once you have a rug, use the colors in that for pillows and throws to coordinate your look.

I agree with Ingrid that the leather ottoman is a bit much. Look for a rustic wood coffee table, maybe out of reclaimed wood that you wouldn't worry about putting your feet up on if you want. For the accent wall behind the fireplace, how about pulling some greys out of the fireplace stone and go a bit darker? Maybe a wood piece for tv and electronics? The overall vibe is going a bit masculine, if that is what you want. Nice space to work with!

Repaint the room in a taupe color and get an area rug in that pulls it together. Lose the curtains and leather ottoman, it is too much. Look for a coffee table.

Here is my suggestion: the beige in the stone and the leather should be a starting place for the walls. I would pick either a much lighter version of beige in the sofa or a color that leans toward taupe as maggie suggested. Neither the yellow nor the blue work in your space. Lose the curtains, ottoman, and the painting, which do not work in that space either. You could bring in a dusty blue or a light coral in pillows and a rug.

Taupe for whole room, as suggested above. I don't think you have a good wall for an accent wall.

The yellow can stay if you paint the blue wall the gray color from the pillows. I would select an off-white linen color for the drapery panels that work with the stone on the fireplace.

Morning! No, I wouldn't leave the yellow. You might want to post a pix looking into the kitchen since they share the same paint color. Go with a taupy tone...

As for the drapes, I am ALWAYS pushing these but you cannot beat them for an expensive look (linen) lengths and price. I've used them for umpteen years in several homes and have the beige. The beige is a shade that also works with grayish beiges....I have that tone now. I never would use the tiebacks included....awful look. They also send iron on fusing so you can hem them to your length. They're probably the only drapes that come in extra long lengths (118") that won't break the bank or demand custom. Cut the tabs off, turn over the material, hem and use clip rings. Tabs are not a great look IMHO.

I notice that online they don't have the beige ones at the 118" length but do the gray. I'm not sure why since I've bought them before. You might check into that. http://www.ikea.com/us/en/catalog/products/20111974/

Witih the drapes right next to the stone pattern, I'd prob avoid any patterns....just too much going on. Save pattern for a rug and pillows.

Oh, meant to post this closeup pix of the drapes too....these are mine. You don't want shiny or silky textured drapes, esp with that stone...stick with linen, more cotton textures.

LOL...that was quick with the pix! :) Yeah, that yellow isn't doing anything for the kit either. So with the drapes, either the beige or gray will probably work from seeing this shot of your sofa. This could be a neat room with a colorful rug and pillows for accents. Black and white art/prints/photos would be sharp.
