I found it difficult to find a colour I liked in the tan/beige spectrum. Just a suggestion, if you're looking for something warm and cozy you could go with white, and there are so many variations that you could get one that leans towards warm rather than say ice blue. Then use accessories (pictures, soft furnishings) with colours to help bring some colour and more warmth in the room. To that, add some lighting (table and floor lamps, which you appear to have already) and you could get the room you're looking for. It might sound like more work but it really isn't because trying to find the right colour can be a very long and laborious process. Much longer than finding an orange cushion, should you want orange back in your life I have to deal with smaller spaces (yours look small) and had been through a lot of colour swatches trying to find the right one. My original music room was about 13x13 and I painted it a midnight blue, which was totally awesome for a few years, but then I went grey and the room is much brighter and more inviting to use on a daily basis. The dark blue colours was great but it definitely made the room feel smaller.
