A kitchen that is decorated in the futuristic style is usually white, metallic and glossy. Sometimes there are some wood elements but they are unstained. If things are colored make sure they are in a pure primary color. For instance choose a pure fire engine red rather than a pastel rose or your kitchen will start looking rustic rather than futuristic. Bright tangerine orange looks better than pumpkin, or your futuristic walls start to look more seventies. Keep the colors as pure and basic and as glossy as possible.
Big, heavy stainless steel appliances have that air of modernism around them and they are very minimalist-looking. You can also get counters, steel cupboards and tables in brushed metal to help your kitchen look even more space age.
Pairing brushed metal details with grey or white Carrera model or white formica like surfaces is also very futuristic looking. For an added touch of Kubrick-like retro-future modernism add a clear Lucite table or chopping block or buy chairs that look Victorian but that are actually molded out of white or clear hard plastic.
Color play and neon lighting can also do a lot for making a kitchen look like it is from the future. One idea is to make a kitchen all white and then make the counter and back splash a bright blue and light it with neon. The effect is very tidy and space age.
Another way to make a kitchen look futuristic is to keep everything white and then paint exposed walls a deep blue or black or even a pumpkin orange.
Fridges with glass doors or smokey colored glass doors can also be space-age looking. Another interesting effect is to add shelves made out of clear, orange, yellow or light blue plexiglass. Lighting can do a lot to enhance the space age glow of glass shelves as well. The hotter and more pin-pointed the lighting is, the more glamorous and showcased it will seem.
Making displays of things that are shiny and keeping it functional also makes your kitchen more futuristic. If you have state-of-the-art gadgets it does not hurt to display them as well.
Futuristic kitchens also have very clean straight lines or geometric shapes to them in general. That is why it is so difficult to make a futuristic kitchen look good in a crooked old Victorian. You are better to try this look in a condo.
