Choosing paint is can be a big undertaking, but my cabinetry paint guide will make the process a lot easier. I've picked several options in blues, grays, greens, whites and black for you to pick from. This should simplify the task and hopefully the decision process will be fun.
Love the countertops, the pendant lights, and the color of the cabinets. IMHO, white is not a good cabinet choice, because if you cook a lot, they look dirty too quickly. I think that the backsplash needs to be a different color, something darker, to jazz it up a bit.
