I've been working on some skins, and I want to remove the color (red) your units take on when they are received.
Those are the team colors. You can turn them off by entering the console command "game.teamcolors 0" in game.
gameprefs.ini - TeamplayColors = -1 // 0 change to 0.
GBD's way will make them always off. Be sure to copy that line into localprefs.ini and edit it there because gameprefs.ini is asset checked.
Also, a unit will only use team colours if it has a mytexturec0.pic
The mytexturea0.pic can also be used to illuminate areas of the unit using a mask.
Subtle use of this can be used to reduce the amount of team colour on areas of the skin.
a0 is also the glow control, so be careful in its use.
I forgot that textures without c# versions don't have the color change. That is why most textures are 00 to 09, for the a0-a9 and c0-c9.
