Hate the yellowish pipboy menu color hud?
With this tweak you can change the menu hud color to what ever you want.
I was looking around the full ini setting that been posted on nexus.
I don't know is this has been posted or used on mod tools on nexus since I don't use tools to fiddle with my ini's.
To change the Pipboy menu hud in P.A you have to use this ini line's.
You need to post it on the file "Fallout4Custom.ini" the following lines.
[Pipboy]fPAEffectColorB=1.000fPAEffectColorG=0.3029fPAEffectColorR=0.0050
Here's an example what the color looks like with that code above.

The PA main HUD can't be changed with ini's if I'm not mistaken,you need to edit the image to change the color.
Here's a texture mod you can use to change the color which you need to edit with a image editor,the texture mod is from pajonk77.

If you want the same color as your main UI color,look for in the "Fallout4Prefs.ini" with the code line:
fModMenuEffectColorB=1.000fModMenuEffectColorG=0.3029fModMenuEffectColorR=0.0050
Copy the numbers that you have and paste them.
