Colour for Mental Health & Colour Breathing 

Light & colour are vibrating energies, each colour having its own wavelength and frequency.  The different colours are created by light waves of differing lengths.  The colours we see in the objects around us are caused by the light waves being absorbed or reflected off the object.   Without light, there is no colour.  Dark objects absorb more light rays, and reflect less light, whilst objects that look light, are reflecting more light, and absorbing less.

We can use colour in our clothing, our decor, colours of food we eat, or visualise a colour, in crystals or stained water, our choice of plants and flowers, to help us balance and benefit our body, mind and emotions.   We tend to instinctively be drawn towards the colours we need, perhaps being drawn to blue when feeling anxious or stressed.

Complementary Colours

Each colour has its own complementary or contrasting colour.  A complementary colour is the opposing colour on the colour wheel.  This is useful when you are, for instance, feeling blue - you can wear or visualise orange to lift your mood.  When working with colours and feeling unsure, trust your intuition.

Primary & Secondary Colours

The 3 Primary Colours are Red, Yellow and Blue.  Mixing 2 colours will result in the colour between them on the colour wheel.  This is called the Secondary Colour.  If you mix a Primary Colour with a Secondary Colour, the result will be a Tertiary Colour.  Secondary and Tertiary colours will include properties from each of the colours, for example:

Orange          will include properties of red and yellow

Green                                             blue and yellow

Turquoise                                       green, blue and yellow

Violet                                             red and blue
