I took some more pictures. I am NOT married to the rug. But have no idea when I will be able to spend $800 or so on a new rug. The one we have is in decent condition. The current couch is an army green color. I HATE it. I wanted something more neutral, and the new grey is really not that light. It just shows up very light in the pictures. The guy at the furniture store said that the grey microsuede is a fabric that is easy to clean. Its rated for both Water-soluble cleansers and also dry-clean solutions. I am now leaning toward the sample that I marked "brownish-purple". I think I better go with a solid and update to a pattern later when i know where I am at with the rug. Here is a close-up of the rug And the rug with the grey microsuede (it shows up more brownish) The grey on the current green couch Fabric I am leaning towards (I might see what other colors they have this in)

I don't think wine red would be a difficult color to find in home decor. That's supposed to be a silk dupioni fabric - Google image result, I've no idea of source... ETA - just found this @ Macy's site after I posted: https://www.macys.com/shop/product/elrene-all-seasons-18-square-decorative-pillow?ID=2654320&CategoryID=37945&swatchColor=Rouge#fn=COLOR%3DRed%26sp%3D1%26spc%3D53%26ruleId%3D3|BS%26slotId%3D38%26kws%3Ddecorative%20pillows

UPDATE I just received this Fornasetti pillow from Etsy -- it's an outdoor pillow and I intended for use on our deck. However, I kind of like it in my office. What do you think? Perhaps it can live here during the off season.

Your room seems to be gray and greige, but the new rug looks to be off-white with a navy and yellow pattern. Look for pillows with those colors. Choose patterns or solids as long as the colors match the rug. Look for curtains that pull the color up onto your walls. I prefer contrast in my decor, so I show a navy that would stand out from your walls. And, look for some art for opposite the curtains that contains those colors.
