If any of you can't get your previous hair color back, please post or send me a BMP screenshot of your old dye along with a BMP screenshot of the closest you can get to your old dye.
Make sure you use full lighting (Such as inside the tavern) and that it's the same pose. Send more than one pair of poses if you can.
I noticed that one of my character's dyes was a shade lighter, I want to see if that's the same problem everyone else is having. They may be messing with shades like these so they can sell them to us.
