I'm redecorating the living room and just found some great blue velvet curtains. What color should I paint?

I like deep colors-- jewel tones. There is a lot of trim in the room which is currently white & the carpet is off-white. The windows are a focal point so the blue will definitely stand out. The room gets lots of sun (south facing). I'm thinking of either staying in the blue family (maybe even lavendar?) or heading towards terra cotta...
