Blue is the most ethereal of the colours and the one with the greatest number of shades. It represents calm, loyalty and harmony. We live on a ‘Blue Planet’ with its oceans and skies; some stars are Blue and as a colour, it seems to have a universe all to itself.
Blue always evokes the celestial domain, sacrality, freedom and spirituality but also depth and mystery.
In Alchemy it represents the element Air, the mediator between Water and Fire.
