Just wondering whether it's possible to change the skin tone of my character beyond what's allowed by the slider?
e.g. red skin, blue skin, etc.

I noticed that when chems wear off, the screen colours are inverted for a second or so and my character is a really nice shade of blue. Would be nice to be able to get that colour all the time.
Would it take a mod with new skin meshes, or is there a command buried somwehere that I can't find?

Thanks!

You could probably do it by creating a new skin texture, then setting it up as a new race.
