2D Stage background changing colors.

[Smashball2011]

For a Brawl Mod, I'm working on a 2D Stage based on The Legend of Zelda: A Link to the Past, and was inspired by Hylian Skies from Super Smash Flash 2. The Stage so far works quite good, but the problem I'm having is that the background (Which is the main map of Hyrule from Link to the Past) Keeps changing Colors as though I'm going to have a seizure.  The background has the same Image configuration like the other 2D stages I've seen, and I have no idea what's causing the problem.
