Combining colorless base sprites with palettes?

[neptunfl4me]

I was trying to rip Uma Musume Party Dash sprites, and I managed to rip them when I remembered that for some reason it uses the same engine as BlazBlue. However, it seems each sprites comes in 3 parts: a json file, sets of palettes for palette swaps, and a base colorless image.

Is there any conceivable way to put it together to get a colored in sprite, or am I out of luck?

If you have managed to rip them with colors, could I please have those sprites too ? Thank you
