When you have a colour wheel with these basic colours arranged on it, you can create a decorating scheme based on three colour combinations:
Monochromatic or toning colour schemes use tones of the same colour in different hues. This scheme works wonderfully in rooms where you want to create a calm, tranquil setting. Try painting your ceiling a very pale blue, your walls a medium blue and choose accessories in a rich, navy blue.
Harmonious or analogous schemes use colours that sit directly next to one another on the colour wheel. These work beautifully together in a room scheme. Mix blues with purples, or mix oranges with reds.
Complementary colour or contrasting colour schemes use hues that are directly opposite one another on the colour wheel. These colours always look good together, even though they contrast. The colours are exciting when used together. By changing the strength of the colours, the look you create can range from playful to dynamic. For example, blue looks smashing with orange and yellow works wonderfully with purple.
When you understand the colour wheel and master these basic rules, you can experiment with a wide variety of colour combinations and put together stunning colour schemes with confidence.
