Both of those colors look mauve on my computer screen. Is that the color you are seeking?

If you don't like the color of the sofa, why do you want the walls a similar color? I'm thinking that a complementary color would make the sofa fit in better. Are you open to a dark color on your walls? If yes, then aubergine, hunter green or navy or french blue would work.

There are alot of different directions you can go here. Basically you want to make sure that your undertones of your sofa and your paint color don't clash. If you want to take the focus off of your sofa then consider going something dramatic, like aubergine. A cream color on the walls would also be lovely; make sure there is no pink undertone to your cream. You could do midtone blue or green too. Do you have any other rooms painted in your house that you like? maybe you could reuse a color? Are there any other factors to consider like the color of kitchen cabinets or anything like that? If it were me, I think I'd go cream with a yellow undertone, but that's in absence of knowing your carpet color and any other surrounding colors to be taken into consideration.

here you go...

What about somthing like this

door1's pic is great! Something like that with a few pillows, nice art, etc. and you won't even notice your sofa. Don't paint your wall a similar color to a piece you don't like.

Instead of trying to design your room around an ugly sofa, I would make the rest of the room so dramatically beautiful that no one notices the ugly sofa. Come up with a vision for your room (without the sofa in it) and then execute it. Wish I could take my own advice.

Perhaps a silvery-gray or silvery-blue?

Add Black end tables and sofa table, taller and quite substantial silver lamps.

Piper21, Can you post a pic of the whole room and is that the wall that you will keep the sofa on? It would be nice to see what is around the rest of the room.

Yes, we need to know more:-) what is your carpet color and it's undertones, and, is this room bordering your kitchen? If so, what are the colors of the cabinets and countertops?

I agree w/other posters. The colors that you show actually look like "flesh tones" on my screen. I would go w/something more dramatic to make your sofa blend away. Then some pretty pillows and maybe a throw.

I love that color of green for your room. If you like the cottage look the room could end up being like a garden room, and very cheery. I vote light green or cream.
