There is something to be said for an all white kitchen or bathroom. White is often associated with cleanliness, so it makes since to use it in both spaces. When I moved to Southern California from the Midwest I noticed a big difference in the style of kitchen cabinetry in homes. In Southern California, it is very common to find painted white cabinetry versus stained wood cabinetry. Even though the space consists of mostly white, the different textures add interest. In the main image the matte finish of the cabinetry compared to the glossy finish of the subway tile is a nice contrast. 

When designing a white kitchen, adding any other color or even black makes the color stand out and become significant. Adding color can be approached in two different ways. You can select a neutral or pale color that is noticeable, yet blends in with the white color scheme or you could incorporate a much more saturated color that is a strong contrast to the white.

Subway tile seems to be a common choice when designing an all white kitchen. However, I love the marble backsplash featured in the inspiring kitchen above. The dark hardware breaks up the white and adds interest.
