In the first screen is in that way because you need to put all the colors
You need to put colors one by one on the palette
Super Skrull having alot of colors and made a palette is really crazy lol
With scorpion will be very fast i hope you understand
This is the method i used when i make a palette for the first time and when you have all the colors you can save it, then just add the sprite of the char and will work
I use fighter factory ultimate to make chars really recomended super easy to use
