'This uses the life-giving energy of the spectrum to balance the mind, body and spirit.' according to Suzy Chiazzari, international colour therapist, author, holistic designer and Founder of the Iris School of Colour Therapy.
The belief is that light is a life-giving energy that effects our emotions, primary functions and thoughts.
'When we are exposed to a balance of the spectrum of colours, we're healthy. Unfortunatly these days we spend most of our lives indoors away from natural light, and this unbalances us,' continues Chiazaari. 'If this isn't corrected, it can lead to illness, mood swings and depression.'
We all like some colours more than others, but there are certain universal effects colours in our home environment have on everyone, effecting mood, energy levels and metabolism.
For example, red is energising and warming; orange is joyful and sociable, yellow is mentally stimulating and cheering; blue is calming and soothing and violet boosts creativity and is spiritually uplifting.
When you sleep, colours are absorbed through our skin, so the ones you choose for your bedroom, sheets and nightware are important too, Chizzari.
