Yeah, I really hope CC updates their mod, the customization was very well done and useful for a long playtime game like this, and the gameplay tweaks shook things up (but were buggy and unballanced)

They should put this in the DLC....

Replace the Image Files/Folders in the game's directory with the ones here.
I think it's on the Workshop too, so you should be able to just get it there too easily.

Can you tell me the mod file?

It's the Goth Mod portion of it, it hasn't been fully updated to the current version yet but should still work for the most part, but Karryn's regular clothes and such will reappear during certain clothing levels.

Can you tell me the CC mode of this hair color?

The mods are great, they can offer different things ranging from translations to in depth reskins to heavy customisation to tweaks to overhauls of different aspects to whole entire fleshed out (Albeit slightly buggy) new mechanics like a condom/pill/pregnancy system with entire new edicts and features.

Most are a part of one giga mod called CCmod, including pretty much all the things I listed as well as this screenshot but you can pcik and choose what parts to install, it's genuinely one of the best mods I've seen in a bit, big reccomend.

I gotta look into modding KP one of these days, because that is God-tier
