What you could do, if you want, is what I have done. The upper 3/5ths or so "fade" into sunglass color, while the "lower" 2/5ths or so "fade" into clear. I keep saying "or so", because it's not an exact line. This works great. It gives me sunglass protection outside the cockpit, and clear glass for looking at the instruments. But you'll have to be "very" exact with the store, when you tell them what "exactly" you want.
I'd shoot you a picture, but they are 17 miles away in my plane.
