Expert Help with Recoloring Needed

[Arisaka]

Update: I've found the Flag Colors for the Shimazu Clan.

For some clarification, the purpose of this project is to help people who are interested in using the Unit Sprites for STW.
And the reason why I need help in finding the Flag Colors for the other clans is so that other people don't have to get stuck with only being able to use "Ronin Faction" Sprites and avoid having to struggle (like I am right now) with finding the Flag Colors themselves and end up making a mistake in the coloring of the flags.

So please provide some much-needed feedback.
