So long as we're debating magic, perhaps the change represents a increase in power for Gwen? In OS she was relying on Charm Casters spell Book, and therefore their spells were the same color, but as her power increases she instead switches to her natural Anodite abilities.

Ah but Charm Caster was purple wasn't it? Then maybe it's just a sign of a 'mature' spell caster?
