just save that, color it whatever you like and then resave as .TGA format
file name is "w_lsabreSilv01.tga"
use that name, it'll replace the "Silver Lighsabre" with your custom color one. remember, the black doesnt show up ingame, so your just editing the white and grey "glow" effect on that img. turn your monitor brightness up if you cant see it well.
