I would suggest a walk-in pantry. I would keep the uppers and lowers white and do the island cabinetry blue.

I agree with elle4maison

By walk in pantry, do you mean the corner pantry? I would not do a corner pantry. However, your kitchen is quite large so it doesn't look that bad.

Are you intending for the sink under the window to be the clean up zone? Because I don't think you'll use it during cooking because it's so far out of the work triangle. Make sure your prep sink is big and has a garbage disposal.

another option is to move the stove and/or fridge to make an L shape if you don't do the corner pantry.

If you ever go to costco, go with the corner walk-in pantry. I usually don't like them but they're very practical and it doesn't look bad in your layout.
