10 Jun How to choose colours
Use the Colour Wheel
In general, analogous colour schemes—colours next to each other on the colour wheel, such as blue and green—are more casual and relaxing, and work best in informal or private spaces. This is a good strategy for a bedroom, where you want to rest & recover.
Whatever colour scheme you choose, put something black in every room. The black breaks up
all the rest of the colours in the room. Try a black lampshade, a black vase or a black picture frame.
Use the Rule of 60-30-10
When decorating a space, divide the colours in the space into components of 60 percent of a dominant colour, 30 percent of a secondary colour and 10 percent of an accent colour. The walls will most likely be the majority, the upholstery would represent the secondary colour & accessories such as a floral arrangement or throw pillows would make up the rest. The colours are properly balanced and there is a shot of colour (the 10 percent colour)
for interest.
Choose a Colour Scheme from the Largest Pattern in the Space
If you’ve got patterned upholstery, an Oriental rug or large piece of artwork, pluck colours you like from the pattern. For a neutral wall paint colour, look to the pattern’s whites and beiges.
