What Could Have Been: The triology's first release had noted that things were connected in such a way that there would originally have been three games with linking portions.
Oracle of Light / Mystic Seed of Courage was to be the third one and would dealt with actual dimension travel between a 'dark' and 'light' world; each representing a split in a time line (Ages and Seasons caused by some time ripple) that would have lead Link to the realization that he was actually in the same world but one had a lack of color and the other had too much.
Accordingly the color had a way of changing the dark world and the light worlds respectively by giving/taking it away to open paths, move doors, and even repainting reality.
