Found this interested GFX edit for Falco where Fire Bird looks like so:

But when I open the .pac file in PSA and compare it to the vanilla .pac file, I see no different values in Falco's UpB.

Check also ef_falco tree for the list of the effects in brawlbox. In each of these graphical effects has their particle folder inside where you can edit the color. Some parts of the effects gets edited.
