Ah, my good fellows!

Edit: clarity

Edit 2: replaced links with jpgs.

The default black hair is actually fairly light...but! There is a way to get it darker. That is through greying. I know that sounds counter-intuitive, but it works. Go to greying, select black, and then go down to greying intensity and move the slider all the way to the right.

You might be thinking I got it backwards, but I'm certain I don't. Moving the slider to the right for any other stat (like freckles, makeup, etc.) increases the value.

Here are before and after photos:

the colour is the way your game system generates light... results will differ on PC but its still a valid option

p.s, your images have to be in jpeg not png for this forum to attach... you may also have to drop the size by 50%

nice character

It worked! Thanks for the info and compliment!
