Once you click on your chosen room a selection of colour groupings of various depths of hue appears, all based on the colours featured in your room selection. Then select one of the colour groupings and begin to experiment by adding these colours to different areas of the room, which now appears in outline form. Add these same colours to different room outlines, all of which are based on the images featured in the book.
Useful for leisure use at home and to demonstrate inspired colour ideas to others. There really is no limit to what you can create and there is the added advantage of not being restricted to a particular paint range.
