Yes, the colors represent the type of damage (fire, water, earth, air, and spirit). These elements have different damage values when you attack elemental enemies.
You can deal 0 damage if it’s the same element, half damage against elementals that are resistant to that element, and double damage against elementals that are weak to your spell’s element.
But I think I’ll try to make this clearer!
