LOL, now I see the problem! x'D You put two masks in the same spot, didn't you, Silver? (I'm not making fun of you!)
If you did that then just fill out the spots that were painted in black on the second mask, not over where the colors on the first mask were placed.
I don't even know what I'm talking about.. >_<
So really, did you place a color in the second mask where one color was in the first mask? Example: red at the bottom left corner in the first mask, and blue in the same spot in the second mask.
Hope I made sense there. :3
