Try an amber color instead and it won't turn the whole world nuclear green when you turn on your lamp.
The color of your Pip-Boy light is tied to the color you set in the options menu. PC specific: Instead of holding V to enter the build menu you can hold the center mouse button/wheel if you want. There's an auto-save setting where you set a timer (default 10 minutes) and after that time is up the next time you look at your Pipboy and back out of the menu it'll save. I noticed that my mostly empty fusion core (power armor battery) sold for the same price as a fully charged one, so never let those completely deplete if you can as I suspect an empty is worthless. You can tag materials you need, so like I tagged copper because I want to wire shit up, so now when I look at a lamp that can be broken down for copper there's a little magnifying glass next to its name.
You can take mods off of guns you find, but I haven't messed with it yet, you might have to craft the base mod first but maybe that's free, if not it's probably cheaper anyway.
The critical hit bonus thing you build up in VATS won't miss, so you can use this to hit something super far away and cripple or kill it with ease.
You can pause and save during conversations now, save scum away. Weapon mods you replace go into your inventory, their weight can add up so watch out for that. Headgear bonuses are nullified in power armor, so take the helmet off and put your sunglasses on if you're trying to pass a Charisma check or whatever. Sprinting in power armor drains the battery quicker, don't do that. You can sort inventory when transferring stuff based on things like weight, value, damage, etc (sorting by value could help with the above). Pre-War money is considered junk but is still valuable, do NOT do the above unless you're in dire need of its components.
You can store all your junk materials at a workshop to be broken down to component parts as need be.
