Spheres

Each spell is linked to a couple of color, so they belongs to certain Spheres.

The first color represents the typology of spell and can be only White (Creation) or Black (Destruction).

The second represents the nature of spell and can be 8 colors:

Red, Blue, Light Blue, Brown, Green, Orange, Yellow or Violet.

Each character has an affinity for certain Spheres. The higher the affinity for each color, the lower will be the the Mana cost required to cast that spell.
