OP, a beautiful bike at a very nice price. And I don't blame you a bit for deleting your post (I once bought a bike a day or so after I shared it in that exact same thread); probably could be seen as a service - nobody headed over on account of your post, only to be disappointed to find it had been sold before arrival.
Oh, and black saddle/black tape would look just fine. Note the black edging which brackets each color panel; matching saddle and bar tape could be seen to reflect the same aesthetic.
