Start with the room
Look at the largest existing elements in your room and choose your colour scheme from the patterns you see there. For example, use the upholstery of the sofa, the rug, or a large piece of art, find the colours you like from within the piece. For a neutral wall colour, look into the whites and off whites in these elements.
Use the colour wheel
Colours next to each other on the colour wheel are more soothing, and therefore a good strategy for places like bedrooms and private areas. Colours like blues and greens , or tones of turmeric with yellows, are examples of these analogous colour schemes, which are more often seen in natural settings, and are therefore favoured by the human eye.
Avoid using whites in small rooms that have little natural light. Leave whites to larger rooms with plenty of natural light, as whites can look dirty and depressing if light is lacking. Cosy up with beautiful deep colour and let your small spaces pop.
Always test colours
Always test colours before you start, and always test in all kinds of light. Each paint colour has undertones, and these undertones look different in different lighting conditions. Whether you are using brush outs or sample pots, natural light is the best way to test. Make sure you move your samples around the room to catch all light levels. Check them out at night too.
Compare trim options
Never forget to place your wall and trim samples together and compare a few trim options. The wrong white on the trim can throw off the entire colour scheme and can make your beautiful wall colour look dull or dirty.
