Character Skins for the palette (a question, not a tutorial)

[NYC 4-8-4 Niagara]

so, say, I want to make Fries from Battle For Dream Island (BFDI) as a well-made fighter (Rollano2000's variation is kind of below average and MCA's variation looks terrible, I have played the former and haven't used the latter). there are many variations of his asset, including the variation of him with gumdrops and sugar fries, the variation with blue bioluminescence, the variation with X hiding inside, you get the gist. how should I implement these variations using the color palette? do I have to manually break apart Fries's color scheme and color in these variations? just saying that because I've been thinking of it ever since I joined MUGEN.
