Red is the colour of fire and blood which signifies power and has a stimulating effect. It is also very sensual, hence red roses on valentines day. But red needs to be treated with care in the home. Use it with caution in whole room schemes but it is an excellent highlight or accesory colour. If you want to dilute its potency, try teaming it with black (as in the glamorous couple), white or cooling blue and grey based colours.
