I honestly don't know what causes this glitch, perhaps it involves the way the game palettes colors, but it is rather cool when you look at it. It requires the "Swordless Link" trick to work. Thank's Scythium for another bizarre glitch. He was the first to bring it to my attention.

Purple Haze: In the fight with ganon, lose your sword. Save and reset, and then get out into the field without a sword. Mount your horse and ride to lon lon ranch during the day. Accept Malon's obstacle course challenge, but in the middle of it, use your ocarina on the horse and play the song of storms. A purple mist will appear for about 15-30 seconds, making everything purple sillouettes.
