You may have loads of ideas for different colour schemes in each room of your house and be dying to give them all a try. But stop and think of the overall effect when all the doors are open and you can see into each room. In a smaller house this can tend to look a bit of a mish-mash.
If you'd like to draw the whole scheme together, choose an overall colour for the entire house and then use it in different ways in each room. Larger houses are slightly more forgiving as long as you pay attention to the meeting points.
Choose harmonious colours. You could paint one room blue, the adjacent one a greeny blue, the next purple etc.Alternatively stick to one colour but use a different tone of it for each room, for example, going from a pale shade of blue to a dark one. This works especially well if your rooms open into one another.
