Prismatic Powder

History
Rose and Cobalt found their sample of Prismatic Powder on the monument dedicated to Red in Pallet Town. When they did not know what it was, they took it to Ms. Mary, the owner of the Pallet Town Day Care, but Ms. Mary didn't know what it was either. She theorized that it was some kind of aftereffect of a Pokémon's move, but could not determine where it came from or what its effect was.

When exploring the Lost Woods in Vermilion Forest, Rose, Cobalt, Cira and Victor came across more of it, scattered on the ground around Honey Babe, Serenade, and Ripley.

Rose is currently in possession of a sample of Prismatic Powder.

Description
Prismatic Powder is an ephemeral, sparkling dust. It is almost insubstantial, and reflects the light that hits it into many rainbows. It is also lighter than air, and much of the dust that Rose and Cobalt found in Pallet Town was blown away before Rose could collect it. It does not appear to show any properties that can directly affect Pokémon, at least in the way of items like Silver Powder and the Mystic Water.
