Do you pictures of the room to better help

Your drapes look like they're fine. It's hard to see if they're long enough--do they just touch the floor? That would be the right length. Make sure the paint you pick blends with the color of the drapes and the two chairs. The Edgecomb Gray looks like it would work or you could go with an entirely different color and add pictures and rug to pull it all together. Love the color Sea Salt by SW.

I gave a pics of my house walls pse gave me suggestions which colour paint best house wall outer and inside the living room.

do you have the interior designing and finishes finalized? as I mentioned earlier, everything in the room has to be tied together. I cannot give you a colour for the arch if it is going to clash with the window frame job, or the cabinets or the wood. In case you don't, I can help you with that. we offer consulting services, which is basically this, the help on Houzz, in a lot more detail.
