First of all, your kitchen sounds gorgeous! And I think we have exactly what you are looking for. You might want to try a couple of our 6 inch drum pendants in a nice white/grey combination. The colors would lend to the traditional white of your kitchen, while drawing out your countertop.
You could also use the 6 inch drum pendant in a vibrant turquoise/navy combination. It would add a splash of color and it would also go well with your nautical theme.

Best of luck to you!
