Kitchens are such a fascinating anthropological study of our social habits, and design trends are just the tip of the iceberg! Over time kitchens have radically evolved depending how families socially interact with each other. Kitchens of today are a very neutral space where everyone can participate in creating a delicious meal. In addition people are seeking an open floor plan where rooms flow into each other and they want kitchens to be part of that.
I think one way that kitchens are achieving this open concept is by breaking up the sets. Just like so many other areas of the home matchy matchy is falling out of favor and the kitchen transition is following suit. We are starting to see mixed cabinetry, perhaps the kitchen island is a different color than the cabinets so it looks more like furniture.
Or sometimes the upper and lower cabinet finishes are mixed.
