Add splashes of colour to your walls with purple pictures. Abstract designs will turn a chimney breast of a neutral room into a bold focal point. If your interior already contains mauve hues, match shades in the artwork to create a coordinating scheme. A floral print or landscape image helps to bring the outside in, making it a great choice for conservatories and living spaces. Subtle lilac and lavender tones suit a bedroom, generating a restful atmosphere.
