Help with Gimp

I already tried setting the number of colors to 15 for the very reasons you mentioned. After messing around with it for a bit I might have figured it out somewhat.

I think it has something to do with the background transparency color itself. My Culex sprite had a black background transparency and when I zoomed in I noticed the color was mixed into the sprite itself all over. When I tried using a sprite with a white background transparency, my original problem went away but now I have this annoying white/grey outline surrounding my sprite.

Here's an image of what it looked like before and after the changes.

With black background



With white background (Note: I added green to make it easier to see the white outline



If I remember, I think I saw a Culex sprite in one of your tutorials Zeemis for using ff3usme. By any chance do you remember what you did to get it to work or did you run into the same problems? If anyone can help me with this, I'd be grateful.
