This is a fomod installer that uses the Pip-boy fix from Robert's Male Body and adds the colors from Pip-Boy Light Colours. Without this patch, either you get no colors, or the arm will clip through the pip-boy. The default color from Pip-Boy Light Colours is unaffected. 

Install this patch after both, selecting the color you want in the fomod. 

The original mesh came with this warning, which still applies: "Roberts Pipboy Fix: This is a optional fix that makes it so the vanilla pipboy does not clip with the bodies arm. Warning about this fix, I have used this myself for well over two years without any issues with any other mods including UI ones. But it has not been tested by others, no game breaking issues will come from this (uninstalling should fix any problem) but I thought I should post this warning just incase."

Personally, I've used it without issue for well over a year.
