Pubic Hair is changing colors

Hello,

I just wrote a post about this but it was a typo that made it seem like dyed my pubic hair . Eww gross lol. But my concern was I dyed my hair copper brown back in September and NEVER dyed my pubic hair. But recently I've noticed my pubic hair turning the same exact color a while ago but it only just a small patch which was weird but recently I've started school and going to work and haven't rely had time to pay it attention till the other day I've noticed about 90% was the copper brown color....... is that normal?????
