Ok I tried it and still can't figure it out. I couldn't find any of the tools you mentioned except for the magic wand tool, which won't cover all of my pixels it leaves a lot out that need to be in there. I have version 2.0 would that make a difference? I think I need a extrememly detailed instructions, I might never figure this out, LOL!
Edit: I tried using the magic wand and made it a bright purple, but when I tested it, the black was gone, but the purple replaced it.
