The power of colour has been recognized since ancient times, and can be used in many ways. It can subtly enhance the mood of a room so that it is restful or invigorating, or it may be applied directly onto the body to improve health and mood. A dose of sunshine-coloured light cures winter blues and blue light shined onto babies helps to cure neonatal jaundice. Healing with light and colour is one of the most gentle and easily applied forms of complementary therapies. If you are looking for a easy, effective, and non-invasive therapy to improve your well-being, then this guide is the perfect start for you on your journey to health and happiness.
