It's an awesome combination, I wouldn't want any other color (except maybe lemon).
Yes, the Terra looks a little orange in some pics, but it really is a nice mellow brown. Don't think of Terra as "Terracotta", but think of Terra more as "Earth".
BMWUSA site doesn't do it justice, it's a must see in real life to make your choice.
