Kitchen colours are simply just colours that appear to be best in a kitchen and lends to the overall look and feel combined with all the other elements. The colour should also wear sell over time. The colour could really be anything and you are free to choose any colour you desire.
Some people I know would swear by having cream and beige tones in their kitchen. Others would prefer the earthier colors like browns and light beiges. Yet others would prefer to have their kitchens a spotless and pristine white with maybe black or chrome highlights. And others still would like to have bright vivid colors gracing their kitchens. But they need to decide what colour kitchen cupboards they will be putting is as it will be the big factor as to how the kitchen will look at the end.
You will notice that each and every kitchen will have the mark of the owner stamped. Nowadays kitchen wallpaper is almost unthinkable but during the 60’s it was the in thing. That is why you should apply your personal preference whan it comes to choosing your kitchen colours.
And that's really what choosing your kitchen colors comes down to. It should be something you like, but it should also be something you're willing to live with for the next one or two years, unless of course you're prepared to choose some new kitchen colors and repaint your kitchen.
