Help with some effects

[Seankay]

When you get Brawl+ you get folders with the .pac of the characters effects. I need help with sonic's effects.

So I downloaded a Shadow model and texture but it still has the blue effects from the spin and stuff. So I check the .pac and notice that the images are in black and white, so I say to myself: " If i color it red, it will become purple ingame". And as I never listen to myself I colored it red and it became purpule because it mixed with the red. So do I:
Either delete the blue, and keep the red, either delete the red, and change the blue for a red

But I can't find where the blue is lol

I've read somewhere its impossible to color.
