Various Wiccan traditions assign certain colors to represent the four directions, also known as the four quarters. In most Wiccan traditions, beings known as elementals are evoked at each quarter. Before rituals or spell casting it is a most powerful practice to evoke the energies of the four quarters in a focused way. This gives you power to use these energies to bend matter to your choosing. In alignment with the energies of the four quarters, you can create magick.
