Are you on ps3?
I remember having this problem, but it was always with NPCs, e.g., someone would have a dark face but everything below the neck would be pale, or vice versa.
Maybe you can just continue playing and see if it goes back to normal. If it changed after you saved and reloaded, maybe it will change back to normal after you save and reload a few times.
Yeah, I'm on PS3. Also, I know, I've ALWAYS seen this on NPCs, but I reloaded, quit the game and retried, and I turned off then back on the system, nothing worked. So I started a new file, and sure enough, the pale is gone.
@UnDecaf- While that is true. I seldom if ever traverse through Freeside, so he's of no importance to me. Speaking of him, I laughed when Sawyer says he still regrets adding that kid.
