There's a mod for Alpha 9 called Snappy Dresser (https://ludeon.com/forums/index.php?topic=9279.0). It's a great mod that lets you edit the colour of your colonist's clothing. Unfortunately, the dude who created it is lazy and hasn't updated it for A10. Would it be possible to create something similar? I'm sure it wouldn't be difficult and a lot of people would appreciate it.
