Hi - I would go with a Rust colour in plain - as you already have a few different patterns going on and the rust would go with all your furniture and rug - perhaps something the same or similar to these :)

By the looks of it you need a coffee table and perhaps you have put that green dish and vase on the floor to show that you like this colour too. So, I would suggest you put something like these on your coffee table and also bring that colour green in with some cushions on your sofa and chairs and also mix with some rust ones (the same as the curtains).

The cushions that you already have on your beige sofa - just put some of the plain ones (green and rust) in between and also add, say a couple of cushions on your chairs - perhaps one rust and one green on each - this will tie your colour scheme together then. Love the colours by the way and it's great that you have also mixed some of your patterns - they work very well together. Now you just want those extra Finishing Touches to complete your scheme :)

hope the above helps :)

I would pick something light, like a creamy sand color. Itll make all that stuff pop, currently they are blending into the wall

this is the furniture I bought recently the rug two chairs and couch help me with wall color and curtains and accesseries ;
