I was wondering what color of dye I could use dye my uniform? The khaki color is too bright and it needs to be a bit darker

The uniforms in the movies were custom made by adding just a hint of purple.

I like blue. lol
im gone.

The ones in the movie were made useing a hint of grey (“the boys in grey”) in my opinion here are the best colours for a uniform:
Normal
Grey
Dark Grey
Navy Blue
Black
Brown
All in all nuetral tone colours work best, with the exeption of blue. I also saw red once in a issure of NOW comics, it didnt look half bad. Good luck.
