My living room now...
Some textured rugs I have been looking at:
Texture adds so much interest into a space without having to add colour. Some things to try are fur pillows on a smooth leather couch. (Extra bonus is that this trend has really taken off lately therefore you should have no trouble finding an assortment of colours and shaggy fur). Or, a knit throw on a simple sofa. I also really enjoy textured art which creates so much interest against the flat drywall. Or a shaggy carpet beneath a simple sofa and on a hardwood floor.
Shaggy Pillow Knit Throw
If you're afraid to experiment with colour why not add some interest to your space with an interesting texture?
