Personally, I'd create a new character with the desired hair color you want, and then look at the hex to see how that color is encoded, then just copy the byte array representing color to your desired file. That's essentially what I did to change hairstyles. Let me know if you need further help!

Yeah this is a potential workaround. I made two new characters, with different hairstyles, and found the 12 byte array in sav.dat where they differed (after 0x61697273). I then replaced the array in one save with the array from the other, and that save had the updated hairstyle from the other one. Cna you explain us step by step how did you change that? For started, how did you search 0x61697273 in HxD? I created two identical characters, except for the hairstyles, and then looked at the hex in the two sav.dat's for everywhere that they differed. One such place was right after this highlighted section, and you can see that 0x6861697273 is decoded as ascii characters "hairs" so that was a good hint it was what I was looking for. I then copied the few changed bytes that followed it from one file to the other. But like I mentioned earlier, I looked at the sav.dat for my playthrough and this byte array wasn't even in it, so your mileage may vary.

Potentially, but that might set the game in to a weird state since it's at the beginning and you assign points to your attributes and such. Feel like there'd be better ways to implement it, although that way would be nice since you get a nice visual indication of your changes. I don't really know much about this stuff though, just conjecturing. Yeah this is a potential workaround.

I then replaced the array in one save with the array from the other, and that save had the updated hairstyle from the other one. Would take some time, but a mod could potentially look like an executable that modifies sav.dat, if it's hard to implement the functionality in game. Think a better solution would be to try to unlock the dev console in game, but I haven't looked in to that and don't even know if there is one. what software did you use? I tried with notepad++ with a hex plugin, but I feel like it doesn't display things correctly. I'd love to be able to just swap appearances between 2 created characters. I'd say any hex editor would do, I just happened to have one on my computer already called HxD, but probably the only thing that really matters is copying the correct values. Will probably take some trial and error though, because I opened the sav.dat for my current playthrough and it was a bit of a mess compared to the two new saves I had created (couldn't even find the array for hairstyles that I mentioned). I still feel like the best route is to unlock the debug console, because in the witcher they had commands for editing appearance that wouldn't require restarting the game a bunch like editing sav.dat would.
