I think grays and blues would look great! here are a few accents that may go with your yellow color. I also think that if there are a few pops of bright yellow you would be ok! http://deciture.com/antique-styled-floral-wood-metal-wall-decor-3-assorted/ http://deciture.com/artistic-styled-metal-wall-decor-assorted/ http://deciture.com/attractive-styled-metal-flower-wall-decor/ http://deciture.com/peacock-in-print-wall-decor/

You will get huge "orange/yellow" cast off lighting. Anything else you put in there will look as if it is under an orange camping "tarp". Not a great look. As a human, you will probably look like you are in the last stages of liver failure. Honestly. Your skin will take on a strong yellow/orange tone while you are in the area. Not many people can handle that type of colouring. Orange is powerful. You only need a tiny bit to make a huge statement. You only need a lot to make a huge mistake.

I'd suggest dark red curtains if you need curtains at all -- the windows are beautiful as they are, and I'm not sure whether some kind of blind might not give you the ability to darken the room when you want to. On the wall, if you are real fans of any movies or TV shows, three big posters would be fun. Otherwise, I would still suggest using three pieces of art there of that size, all equal in size and somehow relating to each other. Three floral works, or three works in the same style, perhaps. I think a large plain textured rug in a light neutral from one of the cushion fabrics would tie the space together well. You might also consider a lovely low coffee table on the rug to lay out your snacks and drinks for serious media nights.

Consider Grey or white. U could also use geometric or any pattern in mint green
