Nexxus, I really like your choices for center. The tile puzzle block is interesting, but only uses 3 colors. The other gives you a chance to introduce a lot of color. Not sure I can help with color scheme. What or who is the quilt for ( even if "just because you can") should help dictate that. Can't wait to see what you come up with. I am posting my fabric selection here.....will do center this weekend (I hope).
