Green is a balancing colour, in the middle of the visible spectrum. The higher three colours are known as the "cool" colours and are calming in effect, the lower three are known as the "warm" colours and have a stimulating effect. Green is the balance between these two.

Green is the colour of balance and harmony and can, therefore, be helpful in times of stress.

Green is the feng shui colour of renewal, fresh energy and new beginnings. In the feng shui theory of five elements, Green Colour obviously belongs to the Wood element.
