Texture anon here, I'm very sorry for the confusion, I meant to ask about how to paint the palette onto the "grey" one after extracting the model :cc I want to use it outside of MK1 but don't know how to make the textures work
You have to manually color the textures (again, in whichever editing program you use). You can't apply the palettes outside of the game. The best way to do it is screenshot the skin with the color palette you want in game, then compare said colors to the palette file and paint the texture that way (its a texture file, the palette -- located in the skin folder of whatever character model you're extracting; it'll say palette). Or, you can color it in paint mode in Blender after applying the texture onto the model to get a better view on where what color is going where as you're doing said painting (coloring).
