The brown skins work, but if trying to make someone who is black it'll automatically set you to the default light tan after you make the character. There is an onyx tone available though but it looks like the character is made of ink.
With the solid black this is true, but you can use an alternate fully black tone and it'll set the character as you want :)
Yea I'm using the inky black ^^ It is a little weird but it's used by a chultan npc already, so going ahead with it. It's just the black black that isn't working. Probably because it is disabled as a dye choice and conflicting with choice as character creation as well due to that.
The pure black is very unnatural on any person. Some of such options have been disabled by default.
Are you, uh, trying to make someone with a 63 black skin tone?
