You could also put up some blinds to start with , not the metal kind or wood kind, but the fabric kind that fold up when you pull them up. This would help with heat coming in to some extent.
With the colors in the room, I too have a problem with the color of the scarf. I'd have to look at a palet of colors that go with beige and brown. Gold comes to mind, or burnt sienna or the like, but off the top of my head, I'm not good at chosing colors. Have to see them.
