I would suggest you to choose your own favorite color and then mix/match different colors with that. I believe that house is the reflection of our own personality, no one can guide you better than your own soul. Add things which gives you feel of relaxation and must be a unique sign of your own house. As I love greenery so I have added many green xerophyte plants in the central hall. Similarly my favourite color is light link so considering that I have designed wall plates.
