first, consider switching out the mini blind for a woven wood or a nice roman blind
Go over to Tilebar.com and look around. you get 5 samples for $5. Look at the Harlequin and the Nabi and the Montauk lines for starters. see if you like any of those.
here are some other suggestions
scallop shape or a herringbone (these are a 1x6 from Sonoma and are a custom blend of colors)
2x6 Foggy Morning in a herringbone
also from Sonoma,,, they have some beautiful color glazes over there.
I like their grays and blacks blend (above in the arabesque) called Nickel Black. Those would look nice w/your countertop and the flooring.
comes in the gray blend in this scallop shape too
