Change colour of the Cross Straps?

Hi, I've been toying around with modding Napoleon for Muktiplayer purposes (trying to eliminate the inherent superiority of defensive play the game has) and while I am at it fixing the uniform of the Swedish Line Infantry. Ironically the uniform of the Militia is more accurate for the Line infantry than the line infantry uniform they have currently.

I figured out how to switch the model of the line infantry to the Militia, and change the colour of the coat from Grey to blue (though now the Militia has a blue coat as well) I cannot figure out how I can change the colour of the cross strapping from Black to White.

Is this something to do with the Texture map or is there some function in the Database that I can tweak? The latter is easier for me to do.

Also, is it possible to change the headgear of models without changing going through the texture maps? For example if I wanted to switch of a Kiwer Shako for a hat is that possible through the database or would I need to open up a texture map and edit it that way in Photoshop? I'm not good with photoshop so that option is out of the question
