After hooking these I noticed they are all medium values and guess that is okay since I've a light value as the second color and for me to use a dark would over power the piece and to use another light value would be lost with the light value of the back and sashing.
What I might do is reverse the same colors in the 3rd row. So the top left color would be used in the far right square of the 3rd row. And would choose (I think) some different and some same colors or similar colors for row two and four and reverse those too. Well, that's my plan right now but who knows what direction I'll end up going in when the rubber meets the road.
